Monitor both flow rate and flow from pulse output flowmeters in any engineering unit with a push of a button. Programmable, compact, and easy-to-use. Input square wave, sine, or sawtooth frequency. Back-up totalizer lock-out feature prevents accidental erasure. High-speed microprocessor ensures fast and accurate reporting — includes a 4 to 20 mA output for recording or datalogging. Model 32928-76 has two channels to monitor dual flows and display them separately, as a sum, as a difference, or as a ratio.
