mass flow sensor / laboratory
Thermal mass flow meter & controller
These thermal flow sensors are used to measure the mass flow of liquids. They work based on the calorimetric principle.
The digital LIQUI-FLOW® series L30 mass flow meter/controller has been developed for measuring ranges of between 2 kg/h and 20 kg/h. This ideally supplements the larger measuring ranges of the smaller product family (down to small ranges of 30mg/h). The mass flow meter is based on a straight stainless steel 316L tube.
A temperature sensor and a heating coil are fitted to the outside of this tube using thin film layer technology. The sensor signal is obtained from the measurement of the flow which is necessary for a consistently small increase in the temperature of the liquid.
