Measuring principle
  The principle is that a fluid flowing past a heated temperature sensor removes a known quantity of heat as it passes. In a thermal flowmeter, the fluid has to pass two PT 100 temperature sensors. One sensor obtains a reference value by measuring the actual process temperature. The second sensor is a heating element and it receives precisely as much energy as is needed to compensate for dispersed heat and maintain a precisely defined temperature difference. The higher the mass flow past the heated temperature sensor, the more heat is dissipated and the more power has to be input to the element to maintain the temperature difference. Heating current, therefore, is a measure of the flowrate.

Product list
  • Flow meter for medium gas vent-captor 3202.30/xx The vent-captor 3202.30 is an air flow meter for industrial applications. The vent-captor can be integrated into measurement and control systems without additional components. Its function base upon a new calorimetric principle and provides a wide measuring range up to 50 m/s. This vent-captor in a stainless steel housing is particularly suited for use under pressure condition.

  • Flow meter for medium gas inline vent-captor 3302.30 The inline vent-captor type 3302.30 is a compact air flow meter for industrial applications, ideal for small diameters. The measurement of the mass flow bases on the calorimetric principle. The inline ventcaptor is completely resin encapsulated, thus rugged, shock and vibration proof.

  • Flow meter for liquid and pasty media flow-captor 4115.30 The flow-captor 4115.30 is a flow meter for industrial applications which can be installed virtually non-intrusively into any pipe without obstruction of the pipe diameter.

  • Flow meter for liquid flow-captor 4311.30 The inline flow-captor type 4311.30 is a flow meter for Industrial applications. The small compact unit is self-contained and needs no additional parts. The stainless steel pipe itself, running through the center of the inline flow-captor, is the actual sensor element. According to a calorimetric principle a small part of this pipe is electrically heated, such that it is marginally above the temperature of the medium. This heat flow, depending on the flow speed of the medium, is measured electronically and provides an output signal linear and proportional to the flow speed.
