The Model 2135D Flowmeter Interface Module and 2031H Electronic Flowmeter, are used for open channel flow monitoring applications. The 2135D Module and 2031H Flowmeter are connected to a computer or data logger (user supplied), with a serial interface port.
The 2135D Flowmeter Interface Module comes complete with 10 meters of underwater cable (longer extension cables are available if necessary), and Flow-Soft application Software.
The 2135D can also be used with a wide variety of PDAs and Pocket PCs. If the device you wish to interface has a standard RS232 cable, chances are you will be able to use it with the 2135D.
Applications Include:
Irrigation Channels, Effluent Monitoring, Waste Water Treatment, Industrial Discharge Measurement, Ocean, Lake, River and Stream Flow Measurement.
