Greyline Instruments, Inc.
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)
Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Ideal for stormwater, combined effluent, raw sewage, irrigation water and streams. Calibration is simple: enter the pipe diameter or channel shape and the AVFM 5.0 computes the flow volume and displays the flow rate.(read more)
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. Use the built-in control relays or 4-20mA outputs to automatically activate the barscreen rake at preset levels.(read more)
Use this versatile instrument to continuously measure, display, transmit and control liquid level in storage tanks and pumping stations, or to monitor and totalize Open Channel Flow through any flume or weir. Mount the non-contacting ultrasonic sensor above the liquid being measured and install the watertight electronics enclosure nearby.(read more)
The MantaRay Portable Area-Velocity Flow Meter measures flow in open channels, partially filled and surcharged pipes using an ultrasonic sensor. It's designed for monitoring stormwater, sewage, industrial effluent, irrigation water and natural streams. The MantaRay displays and datalogs flow rate and total flow and connects to samplers, SCADA and telemetry systems.(read more)
Use the isolated 4-20mA to transmit flow to remote displays, recorders or controllers. The programmable relays can be used for flow control, pump protection or flow proportionate pulse. Calibration is easy with the built-in 5-key calibrator. Display and totalize flow in your choice of engineering units (gallons, liters etc.)(read more)
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. Use it for flow surveys, I&I studies, stormwater, irrigation water and sewage.(read more)
