Transducers for flow or batch control may put out a pulsed / AC signal or a conditioned analog signal such as 0-1 mA, 4-20 mA or 0-10 V. Laurel offers digital panel meters for all signal types normally associated with flow meters, with scaling to display in engineering units, such as Gallons, GPM, or liters/sec. Flow meter capabilities include square root extraction for use with differential pressure flow meters, custom curve linearization, rate from successive readings, totalizing from rate signals, analog outputs tied to the reading, and relay outputs for alarm or control.

Batch control (or batching control) is used for repeatitive fill operations. Laurel batch controllers are available for flow meter signals with a pulse output or an analog output (0-1 mA, 4-20 mA or 0-10 V). Batch control is provided by two relays, one of which can serve as a pre-warn relay to slow down filling near the setpoint. The display can be set to show the current batch total, grand total, number of batches, or flow rate. All displayed values are scaled to engineering units of volume or flow.
