The Hach Sigma 930T Remote Communications Flow Meter provides a reliable, cost-effectivewireless flow monitoring solution. It is ideal for long-term/permanent flow studies or temporary installations in inaccessible locations. > Automatically corrects for temperature effects Օ Uses patented drawdown correctionӔ to correct the effects of velocity on accurate level measurement Advanced Doppler technology avoids signal dropouts and ensures accuracy in low-flow, full-pipe, or reversed-flow conditions > Flow Products ՕContinuously monitor data in real time or retrieve data automatically for later analysisAlarm...

Flow Products Its rugged design, low-profile probes, and one-year battery life significantly reduce site visits.Choose up to two area velocity sensors, or one area velocity and one level backup. Whether you require redundancy in a single pipe or level and velocity in separate pipes, youll profit from new performance levels in a single meter. Industry standard MODBUS ASCII protocol has been incorporated into the American Sigma940 Flow Meter. The implementation of the MODBUS protocol allows your SCADA or DCS system to directly communicate with the 940 Flow Meter without the use (or additional cost)...
