Insertion, in-line and portable models: MASS FLOWMETER FOR GAS
This model is a Thermal Mass Flowmeter for gas measurement. Its measuring principle takes advantage of the fact that calorie amount taken away from the heated sensor by a fluid flow is correlated to the mass flow. It comes in three designs – retractable insertion, in-line, and portable type. The sensor inserted in the process line samples a representative flowrate across the line to infer the total flowrate.
