FAQ

Q: What is the standard lead time for a non-standard flange process connection?

A: Custom flange adaptations typically require a four to six-week engineering and manufacturing cycle before shipment.

Q: Does the factory provide material traceability documentation for regulatory compliance?

A: EN 10204 3.1 material certificates for wetted metal parts are available upon request.

Q: How often does the internal sensor structure require factory recalibration?

A: Annual verification is recommended, though actual intervals depend on fluid abrasiveness and specific process cleanliness standards.

Q: Can the control valve be serviced or replaced independently of the flow sensor?

A: The modular design allows field replacement of the valve actuator assembly without disconnecting the primary sensor tube body.

HNF90 Mass Flow Meter
Specific Parameters	Value / Description
Measurement Principle	Based on the Coriolis Effect. When fluid flows through the vibrating measurement tube, a phase difference proportional to the mass flow rate is generated. The sensor detects changes in vibration frequency, phase difference, and amplitude, directly calculates the mass flow rate, and determines the fluid density through synchronous vibration frequency.
Nominal Diameter Range	DN01, DN02, DN03, DN04, DN08, DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN150, DN200, DN250
Wetted Parts Material	316L Stainless Steel (default), options include 904L, Titanium, C4 Steel, Hastelloy, Duplex Steel, Tantalum, etc.
Connection Method	Threads (NPT, UNF, G thread, DIN sanitary thread), flanges (HG/T, GB/T, ASME, EN, JIS), sanitary clamps (Tri Clamp), etc.
Maximum Measurement Error	Liquid: ±0.1% ± (zero stability / actual flow) ×100%; Gas: ±0.25% ± (zero stability / actual flow) ×100% (accuracy classes available: 0.15, 0.2, 0.5, 1.0).
Measurement Range	Range ratio up to 100:1 (low-frequency sensors up to 1000:1), specific maximum flow varies by model and size (e.g., DN08 max 55 lb/min, DN250 max 66138 lb/min).
Maximum Process Pressure	Up to 96 MPa (depending on the model and size, for example, the small diameter PU type up to 87.5 MPa, large diameter flange type minimum 4 MPa).
