FEATURED PRODUCTS

DFM 5.0 - Doppler Flow Meter

Measure flow from outside a pipe. The Greyline DFM 5.0 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 pipe 1/2' (12.5 mm) Inside Diameter or larger. The electronics/display enclosure can be mounted nearby.

Portaflow - PT400 - Portable Transit Time Flow Meter

Recommended for clean fluids like water, glycol, oil and most chemicals. Sensors can be mounted without shutting down flow and there is no obstruction or pressure drop. The ultrasonic signal travels through all common metal and plastic pipe materials. Flow rate and totalizer are displayed continuously along with battery status, signal strength. Press one key to instantly change the units of flow measurement (e.g. from gallons to liters). Real time ...

FEATURED APPLICATIONS

Pump station level controllers for pump staton call outs - Water and Wastewater - Pumps & Pumping

Town operators were plagued by high level alarm call outs at two new sewage lift stations. Read how they used Greyline`s hybrid ultrasonic level controllers with dual sensor capability to put an end to level alarms.

Level indicating transmitter for swimming pool level control - Water and Wastewater - Swimming Pools

A Surge Tank is used at the Okatokes Rec Centre Swimming Pool to regulate pool level. By monitoring level in a surge tank the non-contacting Greyline LIT25 Level Indicating Transmitter controls makeup water flow through a solenoid valve.
