Liquid Flow Control Systems Directory

The Liquid Flow Control Systems Directory section from Process Controls and Instrumentation Buyers Guide is a comprehensive directory resource.

Measuring the flow of liquids is a critical need in many industrial plants. In some operations, the ability to conduct accurate flow measurements is so important that it can make the difference between making a profit or taking a loss. In other cases, inaccurate flow measurements or failure to take measurements can cause serious (or even disastrous) results.

With most liquid flow measurement instruments, the flow rate is determined inferentially by measuring the liquid's velocity or the change in kinetic energy. Velocity depends on the pressure differential that is forcing the liquid through a pipe or conduit. Because the pipe's cross-sectional area is known and remains constant, the average velocity is an indication of the flow rate.

The Liquid Flow Control Systems Directory provides a comprehensive range of liquid flow control products featuring ultrasonic, variable area, controllers, monitors, meters, indicators, switches, alarms, doppler, positive displacement and universal to provide flow control systems solutions from world's leading manufacturers.


3200U Ultrasonic Flow & Level

Ultrasonic microprocessor based open channel flow monitor, 2 digital displays, 3 relays, 4-20 mA isolated output, NEMA 4X surface mount enclosure.

AVFM-II Area Velocity Flow & Level Monitor

Display, Transmit and Totalize Open Channel Flow in Pipes and Rectangular channels. Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir.


DFM-4.0 Doppler Flow Monitor

Measure flow from outside a pipe. The DFM-4.0 is ideal for "difficult liquids" that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives.

Digital Flowmeters by Metertek

These meters read flow rate, pressure, and accumulated flow volume. The output is digitally displayed in both the F100 and F300 series meters. The F300 output can also be read as industry standard 4 to 20 milliamps for remote computer/PLC monitoring.

Flowmeters, Flow Switches, Flow Indicators

About Us

Our Publisher and Owner has been involved in the Canadian Process Control Market for over 35 years. As a former publisher and founder of one of our competitor's print publications in 1992 he left and began his own print magazine known as The Complete Process Products Book which evolved into Process Controls and Instrumentation News. In 1999 we created which contained an online Buyers Guide. We further evolved to the web site you see today and began to develop and maintain web sites for our clients. We introduced The Process News in February 2004 with a worldwide circulation of 43,000 readers providing up-to-date information on the latest products.
