DF-DL Digital Flow Meter with Batch Controller

Brand: KOBOLD Instruments, Inc

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

Two relays with SPDT contacts are included and may be utilized for various functions. Freely-adjustable switching points, hysteresis, window point, and switch-on/switch-off delay may be set as desired for each relay. 

One relay (S1) may be used to execute flow monitoring, total volume monitoring, and fine batch volume or pump control. The second relay (S2) is commonly used for batching control and opens once the desired batch amount has been reached. 

The batching process can also be immediately interrupted and then quickly resumed by using the onboard Start/Stop switch. 

If a small correction quantity is desired, a bypass valve can be controlled using relay S1.
