Débitmètre et instrument de lecture électronique
Modèles 2135 et 2031

The model 2135 readout is a real time hand held microprocessor controlled data acquisition unit. When used in conjunction with our flowmeter sensor, this battery operated waterproof unit displays current velocity in cm/sec, ft/sec. m/sec, or knots. The easy-to-read two line liquid crystal display also gives you total distance traveled. The microprocessor based unit provides an event timer with external start/stop freeze display switch.
The 8 oz. flowmeter sensor Model 2031H is made of rugged non-corrosive materials, measures flow rates from 2cm/sec to 7.9 m/sec, is self-orienting and has unlimited depth capabilities. Optional 128k memory, RS-232 and software for data recording.
