Model: ES -Heinrichs, Electronic transmitter

The ES transmitter is used in combination with the BGN, BGF, and TSK series of flowmeters, as well as in BA level meters. As a result, the areas of both volume and mass flow rate as well as level measurement according to the
displacer principles are covered. For the installation in potentially explosive gas atmospheres, the ES transmitter is intended for use in an enclosure providing a degree of protection of at least IP 20.


The transmitter can be used with the following Heinrichs instruments:

  • Variable Area Flow Meter BGN and BGF
  • Flap Flow Meter TSK
  • Liquid Level Meter BA
  • Density Meter DWF


Robust, durable, potted electronic
The geomagnetic field is compensated by a differential measurement
