General Information
The non intrusive system application is now preferred in the open channel flow measurements field. For this reason the SGM-LEKTRA developed theFLOWMETER unity to best meet the application requests. The FLOWMETER unit offers, together with its compact size, a easy start up. FLOWMETER is an ultrasonic flow transmitter, temperature-compensated and suitable for connection with MODBUS RTU acquisition systems. FLOWMETER in addition to an analog output includes two freely addressable relay for flow threshold or for totalizer pulse output.
