The electronics/display enclosure can be mounted nearby.

FEATURED APPLICATIONS

Flow Monitoring for Golf Course Irrigation

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.

Differential level transmitter for VFD pump control & flow measurement

An Ontario municipality deploys Portable flowmeters to solve flow rate discrepancies between sewage pump station effluent and lagoon influent flowmeters. Faced with suspension of construction permits due to flow rate uncertainty, the Township of North Glengarry called on Greyline Instruments to help troubleshoot two permanently installed flow meters.
