ENDRESS + Hauser 's Prosonic open-channel flow rate measurement devices are designed for irrigation channels. The Prosonic ultrasonic clamp-on flow meter is used for large pipes.
In situations where higher accuracy is required, Promag magnetic flow meters are the choice. Promag can be powered either from 220Vac mains, or 24Vdc. 24Vdc is typically used with solar cells for operation in remote area. Both instantaneous and totalised flow rate readings can be transmitted via GSM, GPRS or the Internet using the fieldgate.
Endress+Hauser also offers pH systems and conductivity meters for monitoring the salinity of water. The range of level measurement devices includes the Waterpilot for measuring groundwater level in bores (with pump control) and the Prosonic ultrasonics for monitoring dam levels. Pressure transmitters, data loggers, signal conditioners, and surge protection devices are also available.
