Thermal energy flowmeter for gas KEC - Kobold

The new flow sensors KEC work according to the calorimetric measuring principle. Therefore an additional temperature and pressure compensation is not necessary. Due to its robust design, the aluminium die cast housing, the robust sensor tip made from stainless steel 1.4571, new KEC are suitable for demanding industrial applications. Contrary to the previously used bridge circuit, the newly developed evaluation electronics records all measured values digitally. This allows very precise and fast measurements with a wide temperature range of up to 180 °C. The measuring span is 1... 1000 and enables therefore measurements in very low as well as very high flow speeds of up to 224 m/s.

KEC has an integrated Modbus output as a standard with which all parameters like Nm³/h, Nm³, Nm/s, Nl/min, Nl/s, kg/h, kg/min, ft/min, °C, etc., can be transferred. All parameters can be adjusted directly at the instrument (via display) or via Service Software.

There are also 2x 4-20 mA analogue outputs available for flow and temperature and a galvanically isolated pulse output for the total consumption. A remote diagnosis can be carried out via Modbus and all relevant parameters can be checked and changed if necessary. So it is possible to change e. g. the gas type, the inner diameter, the scaling and so on.
