More informations

Model DB50 thermal mass flow meters and counters report and measure mass flow rates and totals of non-aggressive gases, regardless of gas pressure and temperature.

Process gas flows around a heated temperature sensor that is encapsulated in glass. As a result, the sensor dissipates heat which an electronics module returns to the sensor to maintain it at a constant temperature. The dissipated heat energy is proportional to the mass flow rate of the gas and is output as a 4 to 20 mA signal by the electronic utilizing calibration curves and process parameters stored in the instrument.

The 4 to 20 mA signal is routed to secondary evaluation devi­ces and provides the flow rate information. An additional pulse output with a pre-defined pulse value is used for totalizing purposes. Mass flow rate, total or temperature may also be displayed on an integrated back-lit display if required. The instruments are supplied with a 1/2” thread compression fitting and can be installed and disassembled under pressurized conditions.

Typical applications

Model DB50 thermal mass flow meters and counters provide flow measurement of non-aggressive gases in DN 25 to DN 600 pipe systems. Their rugged, heavy-duty design and easy handling and operation make them the right choice for measuring and monitoring compressed air consumption levels. They also provide measurements of other suitable gases such as: nitrogen oxygen, argon, helium and carbon dioxide.
