FAQ

Q: How does the Temperature Liquid Turbine Flow Meter handle viscosity fluctuations?

A: Significant viscosity changes alter blade hydrodynamics; specialized calibration curves are recommended for liquids exceeding 10 cSt.

Q: What packaging methods prevent rotor damage during international transit?

A: Rotor locking structure and anti-static packaging are used for transport protection inside heavy-duty dual-wall cartons.

Q: Are material test reports provided for the pressure-retaining components?

A: EN 10204 3.1 material certificates detailing chemical and mechanical properties are available upon request during ordering.

Q: How are calibration records archived and retrieved for future audits?

A: Calibration records are linked to each serial number and stored digitally for at least five years.

HNF20-AC Temperature Liquid Turbine Flowmeter Parameters
Specific Parameters	Value / Description
Measurement Principle	The principle diagram of the HNF20-AC temperature liquid turbine flowmeter is shown. A turbine is installed in the center of the pipe, supported by bearings at both ends. When the fluid passes through the pipe, it impacts the turbine blades, causing the turbine to rotate. The rotational speed of the turbine is directly proportional to the flow rate of the fluid. The liquid flow drives the turbine to rotate, cutting through the magnetic lines of force generated by the permanent magnets inside the shell, producing a change in magnetic flux. The sensing coil detects the periodic change in magnetic flux and sends a signal to the pre-amplifier for amplification, generating a pulse signal proportional to the flow rate. The flow rate value is obtained through circuit operation.
