Calorimetric Flow meters

Calorimetric flow measurement is based on measuring the change in flow with a thermocouple. The sensor of a calorimetric flowmeter has two thermocouples, one of which measures the temperature of the flowing gas and the other is heated by an electric current. The flowing gas cools this element and at equilibrium the temperature of this resistor remains constant. The heating power of the element is proportional to the mass flow of the gas. Calorimetric flow measurement is therefore well suited for flow measurement of clean gases and compressed air. The CS-Instruments calorimetric flowmeter is also available with a ball valve so it can be removed from the pressurized tube for cleaning without disrupting the self-process. Calorimetric flowmeters have a large measuring range and can be used with Dn20-Dn300 tube sizes. The measurement principle does not require separate pressure and temperature compensation. The electronics of the meters store all the measured values ​​digitally. This enables very accurate and fast measurements. The new electronics have an integrated Modbus through which all parameters can be read. In addition, the flow sensor has a mA and a pulse output. Flow sensors can also be calibrated for gases other than compressed air, such as: Nitrogen, Carbon Dioxide, Oxygen, Argon, Hydrogen, etc
