Greyline Instruments, a worldwide leader in ultrasonic instrumentation for industrial and environmental markets, is among them.

Key products and industries served

Greyline develops, manufactures and markets industrial flow and level monitoring instruments, including ultrasonic level transmitters, flow meters and open channel flow meters. The company’s primary market is environmental, particularly water and wastewater treatment systems for industry and municipalities. A couple of its key products have been listed below.

  • PDFM 5.1 Portable Doppler Flow Meter: The PDFM 5.1 is ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. The sensor is easy to operate, and the built-in keypad and calibration menu allow users to set up the flow meter for their application effortlessly. The PDFM 5.1 also works on any liquid containing bubbles or solids, and is recommended for “difficult liquids” like wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. Other impressive features of the PDFM 5.1 are its non-intrusive Doppler ultrasonic sensor, its stainless steel mounting bracket and clamps, its coupling compound and its AC charger with carrying case. This versatile product can operate up to 18 hours on batteries, and recharges overnight.
  • PTFM 1.0 Portable Transit Time Flow Meter: The PTFM is used for calibrations, troubleshooting, flow surveys and as a temporary transmitter to replace inline flow meters. It operates by measuring the “transit time” or “time of flight” for ultrasonic sound pulses transmitted from one transducer to another. Depending on the mounting configuration, the signal may cross the pipe once, twice or four times. For flow measurements, the transit time is compared between ultrasonic signals travelling upstream and downstream. The PTFM Portable Flowmeter is recommended for fluids like water, glycol, oils and chemicals. In addition, it measures and totalizes forward and reverse flow.
