Add Relays to a Greyline Flow or Level Instrument Add Relays to a Greyline Flow or Level Instrument
It's easy to add relays to a Greyline instrument. Power the unit off, plug in the relay board and power back on. The instrument detects the new hardware and automatically loads the menu system for calibration. In this video we add four relays to a Greyline DFM 5.0 Doppler Flow Meter. Following the same procedure you can also add a data logger. It takes just a couple of minutes for complete installation.
Ideal where flumes or weirs are difficult to install. AVFM 5.0 New Area-Velocity Flow Meter
Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. This new flowmeter is designed for municipal stormwater, combined effluent, raw sewage and irrigation water. The new Greyline AVFM 5.0 uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in channels of any shape.
The new DFM 5.0 Doppler Flow Meter from Greyline Instruments measures flow from outside a pipe. DFM 5.0 Doppler Flow Meter
The new DFM 5.0 Doppler Flow Meter from Greyline Instruments measures flow from outside a pipe. The clamp-on ultrasonic sensor mounts on any pipe " ID or larger. The DFM 5.0 is designed for “difficult” liquids like wastewater, sludge, slurries, abrasives or any liquid with bubbles or suspended solids. Calibration and start-up is simple with the built-in 5-button keypad.
This new Model DFS-II Doppler Flow Switch controls flow with a non-contacting ultrasonic sensor mounted on the outside of pipes  inch diameter or larger. It installs in minutes. No pipe drilling or cutting is required and there is no maintenance. DFS-II Doppler Flow Switch
The Greyline DFS-II is designed for pump protection, valve control and flow/no-flow alarms. It is ideal to control wastewater, slurries, caustics, acids and "difficult" liquids. The water tight NEMA4X switch enclosure includes a 5 ampere DPDT control relay, with adjustable ON and OFF set point controls, adjustable time delay, selectable fail-safe operating mode, signal strength and relay status LED's and sensitivity adjustment
Easy Calibration of Greyline Flow and Level Instruments Easy Calibration of Greyline Flow and Level Instruments
Lots of products promise user-friendly calibration systems, but Greyline delivers. See how simple it is to calibrate this Flowmeter.
Golf Course Irrigation Flow Monitoring from Outside a Pipe
A new TTFM 1.0 Transit Time Flowmeter monitors and logs irrigation water pumped to sprinklers at Summerheights Golf Links. The clamp-on flowmeter is used to comply with a Ministry of Environment permit.
Install a 2 million point Data Logger in an existing Greyline instrument Install a 2 million point Data Logger in an existing Greyline instrument
It's easy to add a data logger to Greyline flow or level instruments that are already in service. New 5.0 models auto-detect hardware changes so you simply plug-in the logger circuit board. When the instrument powers up, data logger settings automatically appear in the calibration menu. Greyline data loggers also download directly to USB flash drives - so you don't need to carry a laptop to the instrument to retrieve logger files.
Non-Contacting Solution for Plugged Off Flow Meters
Wax and solids build-up were plugging off pipes and in-line flowmeters at this oil battery site in Alberta, Canada. Read how Petrobakken Energy solved the problem by switching to Greyline DFM 5.0 Doppler Flow Meters with non-contacting ultrasonic sensors.
This new model OCF 5.0 Open Channel Flow Monitor uses a non-contacting ultrasonic sensor to measure wastewater flow through flumes or weirs. It features a powerful, built-in data logger with on-screen flow reports and output to USB flash drives, plus Wind OCF 5.0 Open Channel Flow Meter
The OCF 5.0 works with a non-contacting ultrasonic sensor mounted above the flume or weir. It includes an isolated 4-20mA and USB outputs, 2 programmable relays, a large backlit LCD flow rate display and totalizer. Calibration and selection of flume or weir are made through the built-in 5-button keypad and user-friendly menu system. Your calibration set-up is password protected and flow data and totals are safely stored through power interruptions.
Portable Flow Meter Works From Outside A Pipe PDFM 5.0 Portable Doppler Flow Meter
Mount the ultrasonic sensor on the outside of metal or plastic pipes diameter or larger. The new battery-powered PDFM 5.0 Portable Doppler Flow Meter is designed for fast, easy flow measurement of wastewater, sludge, slurries, chemicals or abrasives.
Easily measure flow from outside a pipe. PT400 Portable Ultrasonic Flow Meter
This new Portaflow PT400 Transit Time Flow Meter is designed for clean liquids like water, oils and most chemicals. Recommended for troubleshooting, spot checks and balancing flow. Clamp-on sensors mount on the outside of plastic or metal pipes and ultrasonic signals are injected through the pipe between the two sensors. Select A or B sensor configuration for a wide range of pipe sizes.
For Clean Liquids PTFM 1.0 Portable Ultrasonic Flow Meter
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. Set-up through the handheld meter is fast with a user-friendly, 5-key menu system. The clamp-on transducers mount on plastic or metal pipes and ultrasonic signals are injected through the pipe between the two sensors. It works on full pipes with diameters from ” to 48” (12-1200 mm).
This new SLT 5.0 Level & Flow Monitor from Greyline Instruments features a non-contacting ultrasonic sensor and a simple, built-in 5-key calibration system. The SLT 5.0 can be used as a level transmitter for tank inventory applications. SLT 5.0 Level & Flow Monitor
Standard features include a non-contacting PVC and PTFE sensor rated for ranges up to 10 m (15 m optional), IP66 electronics enclosure, large backlit digital display, isolated 4-20mA output, two control relays programmable for pump control and alternation, level alarms or flow proportionate pulse. Options include intrinsically safe sensors, plug and play electronics to add functions like 2-million point data logger with USB output and additional control relays.
Start-up of a PDFM 5.0 Portable Doppler Flow Meter Start-up of a PDFM 5.0 Portable Doppler Flow Meter
It's easy to mount the clamp-on ultrasonic sensor and start-up the PDFM 5.0 to measure flow in pipes 1/2" diameter or larger.
Stingray 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. Stingray Portable Open Channel Flow Logger
A new, portable logger for area-velocity flow surveys in sewers, open pipes and channels. Stingray is designed for municipal stormwater, combined effluent, raw sewage, irrigation water and stream flow.
