DF-ZL - Digital Flow Meter with Totalizer

Brand: KOBOLD Instruments, Inc

The DF-ZL flow meter's electronics convert the frequency signal generated by the rotating vane into a numeric flow reading displayed on the top line of the LCD display, total flow volume since reset on the bottom, and a scalable analog output signal. 

Two relays with SPDT contacts are included and may be utilized for various functions. The relays may also be set to activate when a specific volume has been exceeded. 

Freely-adjustable switching points, hysteresis, window point, and switch-on/switch-off delay may be set as desired for each relay. 

Red status LED's clearly indicate the switching status of each relay.
