Stream’s most popular, low price, Batch Controller – ideal for use with Stream Unipulse flowmeters.
The ST-F130 batch controller has two control outputs as standard for two-stage batching or one-stage control with a scaled pulse output. The operator can enter a batch quantity or execute repeated batches very simply. During the batch, the preset value is displayed simultaneously with the batched or remaining quantity. The automatic self-learning overrun correction will ensure an accurate batch every time. On-screen engineering units are easily configured from a comprehensive selection. A wide range of options further enhance this models capabilities, including Intrinsic Safety for hazardous area applications and full Modbus communication.
Batch Controller with 4-20mA output and option of Modbus Communications. In addition to the batch control functions of the ST-130 the F131 offers an analogue output of the displayed flow rate.
The F133 is especially designed for the controlled delivery of varying batch quantities. Similar to the function of a fuel dispenser – the unit incorporates control functions with time delays to sequence control a pump and valve for example software to enable the unit to expect a flow within a certain period of time.
In addition to the functions of the ST-130 the ST-F136 offers an analogue output which corresponds to the status of the batch process – for example 4mA will be generated when the START button is pressed, this value will increase smoothly through the batch – reaching 20mA when the batch is finished. The operator can enter a batch quantity easily or execute repeating batches.
