Greyline Instruments, Inc. - New - DFM 5.1 Doppler Ultrasonic Flow Meter

Measure flow from outside a pipe. The Greyline DFM 5.1 is designed for "difficult liquids" that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The non-intrusive, clamp-on ultrasonic sensor fits any (read more)

Greyline Instruments, Inc. - NEW! Portable! Area Velocity Flow Meter

Calibration is simple: enter the pipe diameter or channel dimensions and the MantaRay automatically computes and displays the flow rate and total on its backlit LCD display. Mount the sensor at the bottom of the pipe or channel and hang the IP67 electronics case above the high water level. (read more)

Greyline Instruments, Inc. - NEW! Stingray 2.0 Portable Level-Velocity Logger

Stingray 2.0 is a compact, battery-powered logger with an ultrasonic sensor. It data logs level, velocity and water temperature readings for flow monitoring through open channels, partially full sewer pipes and surcharged pipes. (read more)

Greyline Instruments, Inc. - PTFM 1.0 Portable Transit Time Flow Meter.

Greyline Instruments - This new PTFM 1.0 Portable Transit Time Flow Meter is designed to accurately measure clean liquids like water, oils and chemicals. Use it for calibrations, troubleshooting, spot checks and balancing flow. Easily measure flow from outside a pipe (read more)

Greyline Instruments, Inc. - NEW - DLT 2.0 Differential Level Transmitter

Reduce costs and simplify instrumentation at treatment plant headworks. The DLT 2.0 can measure both differential level plus flow through a flume. Install one Sensor on each side of a mechanical barscreen to continuously monitor, transmit and control level. (read more)

Greyline Instruments, Inc. - New - PDFM 5.1 Portable Doppler Flow Meter

The PDFM 5.1 includes a non-intrusive Doppler ultrasonic sensor for pipes from 1/2" to 180" (12.5 mm to 4.5 m) diameter, a stainless steel sensor mounting bracket and clamps, coupling compound and AC charger with a rugged IP67 carry case. It operates up to 18 hours from internal batteries and recharges overnight. (read more)

Greyline Instruments, Inc. - AVFM 5.0 Area-Velocity Flow Monitor

The AVFM 5.0 uses a submerged ultrasonic sensor to measure both Velocity and Level in the channel. The sensor is completely sealed with no orifices or ports. It mounts inside a pipe or at the bottom of a channel. (read more)

Greyline Instruments, Inc. - NEW! OCF 5.0 Open Channel Flow Monitor

Continuously monitor, display, totalize and data log flow through any flume or weir. The OCF 5.0 includes a non-contacting ultrasonic sensor that mounts just 8" (203.2 mm) above the flowing water. It is accurate (±0.25%) and reliable (read more)

Greyline Instruments, Inc. - SLT 5.0 Ultrasonic Level & Flow Monitor

Calibration is easy with the built-in 5 button keypad. The SLT 5.0 offers simple menu selection of measurement units (gallons, liters etc.), calculates volume in horizontal round tanks, or flow rate (and total) through any flume or weir. (read more)

Greyline Instruments, Inc. - NEW! DFS 5.1 Doppler Flow Switch

Control Flow from outside a pipe. Recommended for "difficult liquids" including wastewater, cooling water, slurries, sludge, chemicals, viscous liquids and abrasives. The Greyline DFS 5.1 is ideal for pump protection or to activate flow/no-flow alarms. (read more)
