Thermal Gas Mass Flowmeter

A: Depends on the order quantity, generally it is 3~7 working days if the goods are in stock. or it is 7-9 working days if the order quantity is with 50 sets to be produced for all processes.

A: Telegraphic transfer (bank transfer), Western Union transfer, credit card, PayPal, letter of credit, Alipay, cash, custody, etc.

A: On-line order or off line order is ok.You can place credit assurance order here and pay here,we will arrange shipment as agreed date.

A: We will make samples before mass production, and mass production will be arranged after samples approved. Doing 100% inspection during production, then do random inspection before packing, taking pictures after packing.

A: Thermal mass flow meters are most often used for the regulation of low gas flows. They operate either by introducing a known amount of heat into the flowing stream and measuring an associated temperature change or by maintaining a probe at a constant temperature and measuring the energy required to do so.

A: This results in no pressure compensation requirements with a wide span at accuracies up to 1%. Their simple and rugged design mitigates additional mechanical parts for the high reliability and short measuring response times for gas mass flow.

A: Thermal mass flow measurement is an inferred flow measurement. These meters measure heat transfer and then relate the heat transfer to the mass flow rate from the NIST traceable calibration. While calibrating the flow meter, a known amount of gas is run past the sensor and the signal is measured.

A: Calibrations of gas flow meters are performed with primary standards that are based on measurements of more fundamental quantities, such as length, mass, and time. Primary flow calibrations are accomplished by collecting a measured mass or volume of a flowing fluid over a measured time interval.
