一体式超声波明渠流量计 FLOWMETER
The non intrusive system application is now preferred in the open channel flow measurements field. For this reason the SGM-LEKTRA developed the FLOWMETER 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.
· Solution with high price/performance ratio
· Suitable for each channel/Weir also non-standard
· Flow rate and flow totalizer measure
· IP67 execution; IP68 sensor
· MODBUS RTU com. protocol
· Output: 1 4÷20mA analog output
2 relays output
· Power supply 24Vdc
