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 ElectricLR64 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.
In regular piping systems, steam carries large quantities of entrained material. With TLV's SF1 Separator Filter, heating efficiency and product quality is greatly improved by removing condensate, dirt and scale.
The TLV SF1 SF1 Separator Filter is a filter with integral cyclone separator. The cyclone separator (98% separation ratio) eliminates condensate, dirt and scale before filtering. This extends the filter maintenance cycle. Compared to a filter without a built-in cyclone separator, the time between required maintenance is improved nearly three times. The cyclone separator also supplies dry steam, eliminating water spots.
The TLV SF1 is made from all stainless steel construction and includes an easy to clean 5-layer sintered wire mesh filter that maintains an extremely low pressure drop for extended periods. The unit is compact and lightweight, with a ferrule joint clamp facilitates easy cleaning.

There are important factors to consider when defining a thermal mass flowmeter to ensure precision and performance in a gas flow application.
A thermal mass flowmeter has numerous advantages over other technologies for measuring the mass flow rate and consumption of gases. Featuring wide rangeability, pressure independence, extreme low-end sensitivity and ease of installation, they have become widely popular for countless commercial, industrial and environmental applications. Furthermore, by offering a variety of configurations and outputs, TMFMs provide the flexibility and economy to accommodate mostly any type of gas flow application.
To use a TMFM to its fullest potential, give thoughtful consideration to the installation location, the meter’s flow body and which features are best for the application.
The Jordan Valve Sliding Gate Seat is a true value-added alternative to conventional trim designs. Here's why:
Easy Maintenance
Sliding Gate Seats only have one moving component. The seats are not pressed or screwed, making removal simple. Cv values are interchangeable. Valve action is easily changed.
Seat Materials
Jorcote is tougher than stainless steel, offering excellent wear, corrosion, and galling resistance. It has lower friction coefficient than Teflon, providing higher pressure drop capability and less offset. Jorcote seats handle temperatures from sub-zero to 550 ° F (288 ° C). Seats were tested to 1,000,000 full stroke cycles in 70 psi steam, maintaining ANSI Class IV leakage while exhibiting negligible wear.
Constant Seat Contact
Disc and plate are in constant contact. Therefore, there is no 'chatter' inside the valve, less mechanical wear and greater stability at the stroke's low end. Constant touch results in self-lapping and self-cleaning.
Straight Thru Flow
The control element is perpendicular to flow, resulting in lower turbulence and greater trim life.
Short Stroke
In regulators, this results in faster response to input signals, less droop (greater accuracy), and longer diaphragm life. In control valves, the gate seat's short stroke results in less packing wear. Smaller actuators may also be used, resulting in lighter weight, smaller envelope dimensions and less air consumption.
Multiple Orifice Layout
The sliding gate seat's multiple orifice dissipates wear from downstream flow, resulting in longer trim life and quiet activity.
Disc plate overlap
Disc and plate overlap 1/32 "(0,8 mm) around each tube. This creates an area of closure, not line of closure, resulting in better shutoff for a longer period of time, reducing waste and lowering costs.
