For accurate flow measurement of wastewater, sludge, slurries, chemicals, and abrasives, PDFM 5.1 employs Doppler signal processing with ability to filter out noise. Product shows flow rate instantly once ultrasonic sensor is mounted on outside of metal or plastic pipe and can be used for flow troubleshooting, spot checks, or balancing flow. After operator enters pipe diameter, unit will display, totalize, and log data in choice of gallons, liters, or any other engineering units. Read More
Able to measure flow from outside pipe, DFM 5.1 uses doppler signal processing technology and works with difficult liquids, such as wastewater, sludge, slurries, and abrasives, or any liquid with bubbles or suspended solids. Clamp-on ultrasonic sensor mounts on ½ in. ID or larger pipe, and calibration and start-up are facilitated via 5-button keypad. Standard features include backlit display and totalizer, isolated 4–20 mA output, and 6 control relays. Several options are also available. Read More
Installed in minutes without drilling or cutting, Model DFS (Doppler Flow Switch) 5.1 controls flow of wastewater, slurries, caustics, acids, and difficult liquids via non-contacting ultrasonic sensor mounted on outside of ½ in. dia or larger pipes. Water tight NEMA4X switch enclosure includes 5 A DPDT control relay with adjustable ON and OFF set point controls, adjustable time delay, and flow rate bar graph. Switch is suited for pump protection, valve control, and flow/no-flow alarms. Read More
Able to be calibrated to channels of any shape in municipal stormwater, combined effluent, raw sewage, and irrigation water applications, AVMS 5.1 uses 3 submerged ultrasonic sensors to continuously measure velocity at different points. One of those 3 sensors may also monitor water level, or separate non-contacting ultrasonic level sensor may be used in system. Forward and reverse flow can be measured, and sensors are resistant to fouling and corrosion. Built-in data logger is optional. Read More
Designed to measure clean liquids like water, oils, and chemicals, PTFM 1.0 Portable Transit Time Flow Meter is suitable for calibrations, troubleshooting, spot checks, and balancing flow. Clamp-on transducers mount on plastic or metal pipes and ultrasonic signals are injected through pipe between sensors. Operating on full pipes with diameters from ½–48 in., battery-powered unit includes 5-key menu system for setup, backlit display, totalizer, 4–20 mA output, and data logger with USB output. Read More
Utilizing clamp-on ultrasonic transducers, TTFM 1.0 Transit Time Flowmeter accurately measures liquids from outside of metal or plastic pipes. Step-by-step setup menu determines sensor mounting configuration and separation distance, while digital signal processing ensures ±1.0% accuracy. In addition to displaying flow rate/direction, totalizer, and relay status on backlit LCD, non-contact unit provides isolated 4–20 mA output and relays for flow proportional pulse output and flow rate controls.

Equipped with non-contact ultrasonic sensor, PSL 5.0 is suitable for sewage lift stations, wet wells, and storage tanks. Users can also connect loop-powered pressure sensor for redundant sensing in applications with foam or grease. Controller will continuously recalibrate pressure sensor and automatically switch back and forth from ultrasonic to pressure sensor as required. In addition to isolated 4-20 mA output, PSL 5.0 provides 6 programmable control relays and automatic pump run time logging. Read More
Using non-contact ultrasonic sensor, Model OCF 5.0 measures wastewater flow through flumes or weirs with accuracy of ±0.25%. Unit features backlit LCD flow rate display and totalizer, built-in data logger, and output to USB flash drives. With Windows software, meter can display and graph flow reports in fully customizable formats. Additional features include isolated 4-20 mA outputs, 2 programmable relays, and automatic temperature compensation. Read More
