The ADW-FFW Weighing Indicator is to control high speed, high accuracy filling by weight for strain gauge or load cell applications. Either in a stand alone mode or in conjunction with a PLC. 

Operation:

On receipt of the start fill signal weightment is auto tared, and the relay contacts for fast and slow speed are closed, The system is optimised by a routine to ensure that, fast feed is held as long as possible. In-flight compensation is applied to the slow feed and automatically adjusted to minimise final error.

When pre set values are reached, contacts turn off the fast and slow feeds. A 'weight complete' signal is given when within pre selected setting values and time, Auto Tare will take place only when the value falls within a pre set auto tare band.
