Frequency, Rate Meter, Flow Rate Indicator
Laurel Electronics, Inc (Laurel)
Two independent scalable pulse-input channels from 0 Hz to 1 MHz. Channels may be combined arithmetically. One channel can display total while other displays rate. High read rate for control applications: AC line frequency can be measured to 50.0000 or 60.0000 Hz in a few line cycles. Ideal for use as a tachometer or readout of a turbine flow meter.
