Flow Computers

FLOW COMPUTERS satisfy the instrument requirements for a variety of pulse-producing flow meter types in liquid applications.
Alphanumeric displays show measured and calculated parameters in an easy to understand format. Single key direct access to measurements and display scrolling is supported. An EZ-Setup feature rapidly guides the user through the basic setup.
Flow Computers can be programmed for rate/total indication or batching. The various pulse inputs and outputs can be “soft” assigned to meet a variety of common application needs. The user “soft selects” the usage of each feature while configuring the instrument. A 0-20mA or 4-20mA analog output is standard.
