Greyline Instruments

Greyline Instruments is a Canadian manufacturer based out of Long Sault, Ontario that started in 1986. They specialize in ultrasonic technologies. Currently they have over 80 representatives worldwide.

AVMS 5.1 Multi-Sensor Area-Velocity Flow Monitor

Monitor flow through large open channels, partially full sewer pipes and surcharged pipes without a flume or weir. The AVMS5.1 uses 3 submerged ultrasonic sensors to continuously measure both Velocity & Level in the channel. View flowrate and total flow on a large backlit LCD display and connect to devices with (3) 4-20mA outputs and (2) control relays.

DFM 5.1 Doppler Flow Meter

Measure flow from outside a pipe. 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 pipe 1/2" (12.5 mm) Inside Diameter or larger.

DFS 5.1 Doppler Flow Switch

The DFS5.1 Clamp-on Flow Sensor installs without cutting the pipe. The sensor continuously injects high frequency sound through the pipe wall and into the moving fluid where acoustic pulses are reflected back to the sensor from particles or bubbles in the fluid. The unit includes On and Off relay set-points and time delay options with LED bargraph for flowrate.

DLT 2.0 Differential Level Transmitter

Simple solution for barscreen level control at wastewater treatment plants, headworks, pump stations and combined sewer systems. Install a sensor on each side of mechanical barscreen to continuously monitor, transmit and control level. Built in control relays or 4-20mA outputs automatically activate the barscreen rake at preset levels.

ISM 5.0 Insertion Magmeter

The Accurate, Low Cost Alternative to Full-bore Magnetic Flow Meters. Measure flow of water and conductive liquids in full pipes from 3 to 72" (80 to 1800 mm) diameter. The dual pair electrode sensor inserts through a tap in the pipe wall. It can be easily installed in new pipe systems or by hot tap in pressurized pipes with flowing liquids. There are no moving parts so obstruction to flow and pressure drop is minimal.

LIT25 Level Indicating Transmitter

The LIT25 continuously measures, displays, and transmits level in tanks and lagoons, or anywhere you require a level sensor. Includes a non-contacting ultrasonic sensor which is rated Intrinsically safe, a compact watertight electronics/display enclosure, 4-20mA output, backlit LCD display, control relay and simple built-in menu/calibration system.

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.

OCF 5.0 Open Channel Flow Monitor

Monitor, display, totalize and datalog flow through any flume or weir. The automatic flow reporting system prepares and stores daily reports including total, minimum and maximum flow rates. The OCF5.0 has a 2 million data points and downloads to a USB flash drive. There are two control relays, an isolated 4-20mA output and optional IS barriers.

PDFM 5.1 Portable Doppler Flow Meter

It's ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. Fast and easy to operate – you can mount the sensor on the outside of a pipe in less than a minute. Works on any liquid containing bubbles or solids and is recommended for "difficult liquids" like wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. Learn more...

PSL 5.0 Hybrid Pump Station Level Controller

Designed for pump stations, wet wells and tank level control, the Greyline PSL5.0 includes 6 control relays for pump control, alternation, level alarms, dialers or fault alarms. It features a non-contacting ultrasonic level sensor plus redundant sensing with connection of any 4-20mA level sensor. The PSL5.0 automatically stores relay run time reports for pump performance.

PTFM 1.0 Portable Ultrasonic Transit Time Flow Meter

Recommended for fluids like water, glycol, oil and most chemicals the PTFM1.0 ultrasonic transducers just strap-on the outside of pipes from 1/2" to 48" in diameter to provide accurate flow measurment. Calibration is easy with the onscreen menu system, just enter the pipe diameter, wall thickness and pipe material. Battery Operated and includes case.

SFM 6.1 Ultrasonic Slurry Flow Meter

Non-contacting flow monitoring specifically designed for limestone slurry, fly ash slurry, gypsum slurry and many others. The Sensor is mounted on the outside of the pipe so it is unaffected by abrasive slurries or harsh chemicals. There is no obstruction to flow and no pressure drop.

SLT5.0 Level and Flow Monitor

The SLT5.0 continuously measures, displays, and transmits level in tanks and pumping stations, or monitors and totalizes Open Channel flow through any flume or weir. Includes a non-contacting ultrasonic sensor which is rated Intrinsically safe, 4-20mA output, backlit LCD display, control relays and many optional components like 2-million point datalogger.

Stingray 2.0 Portable Level-Velocity Logger

For flow surveys in open channels and partially filled pipes. The sealed ultrasonic sensor mounts on the bottom of the pipe or channel. Stingray operates on standard Alkaline D-cell batteries for up to four years. The built in 130,000 point datalogger stores level, velocity and temperature readings at programmable intervals. Logger software included.

TTFM 1.0 Transit Time Ultrasonic Flow Meter

Accurately measure the flow rate of clean liquids like water, oils and chemicals from outside the pipe. Display, totalize and control flow with clamp-on ultrasonic transducers. Flow rate, flow direction, totalizer and relay status are shown on large backlit LCD display. Comes with 4-20mA output, relays and plug and play options including a data logger.
