FAQ

Q: Is the internal rotor assembly field-replaceable or must it return to the factory?

A: Cartridge designs allow field replacement, though subsequent gravimetric recalibration is recommended to verify updated K-factors.

Q: How are raw castings inspected before use in high-pressure applications?

A: Cast pressure-retaining components are typically inspected using ultrasonic testing to detect internal gas pores or structural defects.

Q: What quality and shipping documents are provided with bulk international orders?

A: Every order includes material MTC (EN10204), pressure test reports, packing lists, and factory calibration certificates.

HNF20-C Gas Turbine Flowmeter Parameters
Specific Parameters	Value / Description
Measurement Principle	The measurement of gas flow is based on the principle of turbine rotation. When a stable state of gas flows through this instrument, it drives a turbine rotor. The rotational speed is directly proportional to the volumetric flow rate. Integrated pressure and temperature sensors are capable of real-time detection of gas conditions, while the built-in high-precision intelligent circuit board will automatically compensate for factors such as pressure, temperature, and gas compressibility. This multi-variable measurement ensures highly accurate standard volume flow output under various process conditions.
