Bronkhorst presents their new generation of ES-FLOW Ultrasonic Flow Meters for low flow rates of water, additives, and other liquid substances. The improved flow meters measure volume flow from 2 up to 1500 ml/min with even higher precision, high linearity, and low-pressure drop, using ultrasound in a small-bore tube. The instruments are liquid-independent, thanks to the unique measuring principle, which accounts for the flow calculation's actual sound velocity. Thanks to the combination of a straight sensor tube with zero dead volume, the flow meter is self-draining. The flowmeter with orbital TIG-welded flanges is CIP or SIP cleanable and now meets 3-A sanitary standards for hygienic applications. More information at the Swanson Flo website here.
Badger Meter ultrasonic flow meters measure flow rate by propagating ultrasound waves into liquid-filled pipes and measuring the reflections. There are two technologies to choose from based on the fluid properties:
- Transit time
With clamp-on technology, the Badger Meter ultrasonic meters reside outside the pipe and bring you flow measurement with:
- Reduced installation costs
- Uninterrupted production
- Installation flexibility across a wide range of pipe sizes

Ultrasonic level transmitters used in dry bulk solids level monitoring are starting to be eclipsed. Radar technology is now so good that it can get a signal and level or distance off of very unreflective media such as polypropylene pellets. Compared to ultrasonics, radar is often more reliable, easier to use, and has lower maintenance requirements. Check out this video from Swanson Flo highlighting the Schneider Electric LR64 and LR65 radar level transmitters.
Mass Flow Measurement of low flow rates, independent of fluid properties.
With the development of the mini CORI-FLOW™ series Bronkhorst achieved a technological breakthrough in Coriolis mass flow measurements and control, by realizing a compact, cost-effective Coriolis Mass Flow Meter/Controller for accurate measurement and control of (very) low flow rates. The unique design of the miniature Coriolis sensor features unsurpassed performance, even with changing operating conditions in pressure, temperature, density, conductivity and viscosity.
Contrary to many other Coriolis flow meters on the market, mini CORI-FLOW™ offers integrated PID control and close-coupled control valves or pumps, thus constituting very compact, cost- and space-saving, precise Coriolis Mass Flow Controllers.

The TFX Ultra transit time ultrasonic meters from Dynasonics / Badger Meter measure volumetric and energy flow of clean liquids, as well as those with small amounts of suspended solids or aeration, such as surface water or sewage. It works by transmitting ultrasonic waves from outside the pipe into the liquid and propagate upstream and downstream. The flow velocity is determined by the difference in the time of flight and is used to calculate the volumetric flow.

TLV Consulting and Engineering Services constructed a clear piping system to visualize the complex bi-phase flow within a steam condensate return system to determine if water hammer can be reduced or eliminated in certain less-than-ideal piping configurations. Sometimes, condensate returns are incorrectly considered to be single-phase flow, but in reality the pipe volume can be primarily filled with flash steam. This creates a two-phase flow condition that presents challenges to the desired action of gravity drainage. Elevation changes in 2 phase condensate return lines are particularly prone to creating condensate backup which can lead to damaging water hammer. The damage can be particularly severe due to the magnitude of condensate mass present as the pipe size increases in diameter.
Two scenarios are examined. First is a commonly seen piping installation of flashing condensate with a vertical rise. Wave action can be seen in the top pipe. It is caused by high velocity steam moving over the surface of the liquid gradually forming waves within the pipe. When the wave grows large enough, it momentarily seals the cross section of the pipe, building a pressure wall behind it. This causes a slug of water to be sent down the line, potentially causing serious damage to piping, valves, gaskets or fittings.
Additionally, in a flashing condensate line, the vapor space is occupied by low energy flash steam which can collapse and generate hammer as condensate rushes into fill the void. In this video, the vapor is non-condensing air, so the violent back slam of condensate filling an instantaneous void is eliminated for safety purposes. The second video introduces a non-ideal method incorporating a drop down loop seal (or DDLS)to help mitigate some water hammer effects. The ideal solution is always to incorporate gravity drainage in the flashing condensate return system design. However, when gravity drainage was not accomplished during the original design, the DDLS may reduce hammer and can be evaluated on a case-by-case basis by a professional engineer for suitability and safe operation. Notice the less violent flow draining into the loop where the wave action was occurring in the upper pipe.
This piping configuration minimizes the length of pipe where surging can occur and reduces the mass of potential water slugs. The result can be smoother flow with lessened water hammer. Although the DDLS is demonstrated using a loop with horizontal piping to enable visualization of the vapor/liquid interface promoting upward flow, it is considered that joining two long radius elbows with no horizontal section between them could further reduce hammer.

Radar level transmitters provide non-contact level measurement. All radar level detectors send microwave beams, emitted from a sensor, to the surface of the liquid in a tank. The electromagnetic waves returns back to the sensor after hitting the surface of the fluid. Radar is the preferred technology for level measurement in many of today’s industrial applications. Newer high-frequency technology (80 GHz) offers advantages in certain application to older low (10 GHz) and mid-frequency (24 GHz) technologies. Selecting the best microwave frequency for your application is crucial. In as much, understanding the relationship between frequency and beam angle is very important.
In this video, Jeff Blair, Offer Manager for level products at Schneider Electric, presents the difference in beam angle at various frequencies. He also demonstrates how to use Beam Angle Calculators to determine beam width at various places in a tank or vessel.

Protecting Draft Range Transmitters from Storms and Wind
Normally, you wouldn’t think about an enclosure in the furnace or boiler area on these applications because they are measuring air flow or air pressure and are not subject to freezing. Pressure measurement in furnace and boiler combustion is critical for safety, efficiency and environmental control.
It doesn’t require heavy wind to cause problems: a 5 – 7 mph wind across the ambient pressure port might cause a 0.1” pressure change, 12 – 15 mph may create a 0.8” change. When the full range is 1 – 2” that can be a 40 – 80% error reading.
Even light wind across the open port can cause 10% error.
For example - in a a draft transmitter with full scale of 1” H2O ...
- 5 – 7 mph wind can cause up to a 10% full scale error.
- 12 – 15 mph wind can cause up to a 75% full scale error.
The pressure range is so small, often just 1 – 2” of H2O or 2 – 4 mm of Hg, that even a light breeze might cause automated dampers to fluctuate or trigger systems to shut down. Using a differential pressure transmitter the reference measurement is vented to atmosphere, where air flowing past the open port creates pressure changes and errors in furnace, heater and boiler combustion box pressure. As part of the Safety Instrumented System these measurement errors can create nuisance maintenance and shutdowns affecting the entire unit.
The O'Brien VIPAK Draft Transmitter enclosure, is a field tested and proven solution addressing the common sources of draft transmitter installation error with:
- Still Air Chamber
- Atmospheric Equalization
- Uniform Capsule Temperature
The O'Brien VIPAK draft range transmitter enclosure atmospherically equalizes the still air chamber for the transmitter and manifold. The pressure inside the enclosure changes at the same rate as the barometric pressure but is unaffected by wind or wind gusts.
The enclosure system also ensures that both sides of the instrument measurement capsule are at the same temperature. Since these instruments are often placed near the furnace, heater or boiler one side can be hotter than the other creating an error in measurement.
A large refinery was experiencing furnace upsets and shutdowns caused by storms and wind in the unit. They installed two O'Brien Draft Transmitter Enclosures on their most trouble prone units as a trial. After a severe storm hit and the units with the O'Brien Draft Transmitter enclosures ran with no problems they installed another 128 protection enclosures. To date there have been no more upsets or shutdowns caused by wind induced measurement errors.
The O'Brien STILL AIR PORT is a critical component of the draft range transmitter solution. It equalizes the still air chamber for the transmitter and manifold, allowing the pressure inside the enclosure to change at the same rate as the barometric pressure and not allowing wind or wind gusts to have any affect.

This video demonstrates the removal and installation of the feedback mechanism of the Flowserve Logix 3800 valve positioner.
Make sure the valve is bypassed or in a safe condition. Disconnect power to the positioner. Disconnect air supply to the positioner. Remove the take off arm and follower arm.
Note, it is recommended that when the positioner is removed from the valve, it is taken to a clean work environment for disassembly and reassembly.
Note, the procedure is the same for both intrinsically safe, or explosion-proof, positioners.
Begin by removing the three screws that attach the feedback assembly to the positioner housing. Install the replacement feedback assembly to the positioner housing.
Note, the orientation is irrelevant since the feedback mechanism has a clutch. Torque the screws to 0.9 Newton meters or 8 inch pounds. Next reconnect the positioner follow arm and take off arm to the valve.
