OPERATING MANUAL TMU-W / UMC4
Removal and exchange of the BE4 Control unit:
When the flow meter is powered up, the device continues using the values stored in the memory device.
Thus, the DSB memory device provides maximum safety and comfort when device components are
replaced.
Due to the device specific parameters saved in the memory device, the control units are not arbitrarily
interchangeable between identically constructed transmitters. Replace circuit boards must be ordered
from Heinrichs using the transmitter’s serial number specification. The calibration data of the sensor are
programmed into the delivered BE4 control panel directly by the manufacture

Input measured variables
Measured Values
The UMC4 measures via the connected sensor the following variables:
mass flow rate,
temperature,
density
A fourth variable, the volume flow, is derived from the measured variables; mass flow rate and density.
Measuring range
The measuring range, which varies according to the used sensor (TM, TME, TMR, TMU or HPC), can be found
in the relevant data sheet and in sections 3.3.2, “TMU-W flow ranges” and 3.3.3, “Density measurement” on
page 13.
The specified measuring range of the delivered sensor is also printed on the devices rating plate.
Note:
Density and volume variables are not available for all sensor types.
The DSB Memory device is situated
on the rear side of the control unit
