What is the difference between PN40 and PN10 high-pressure turbine flow meters? PN40 can be vaguely referred to as PN4.0MPa, but it cannot be said that PN40=PN4.0. The latter part must be accompanied by units. PN40 follows the HG20592-2009 standard, while PN4.0MPa follows the JB/T79.2 standard. Their meanings are the same. Technical parameters of high-pressure turbine flowmeter: flow range: 0.5-20L/m accuracy: ± 1% repeatability: ± 0.3% output signal: pulse; 100 to 2000 Hz K coefficient: 6000 pulses/liter Temperature range: -20 ℃ to 90 ℃ Working pressure: 250 bar Burst pressure: 750 bar (static pressure) Power supply voltage. 5 to 24 VDC, 12 to 24 mA viscosity range: 0 to 1000 CSt process connection: 3/8 "BSP external thread electronic connection: 3-wire ribbon cable sealed in the shell, cable length 15cm liquid contact material: PVDF, Vectra (polyethylene fiber) and Viton shell material. Additional Information: Product Features:

1. ZNLWGY has high accuracy, generally up to ± 1% R and ± 0.5% R, and high-precision models can reach ± 0.2% R.

2. ZNLWGY high-pressure turbine flowmeter has good repeatability, with short-term repeatability up to 0.05%~0.2%. It is precisely because of its good repeatability that high accuracy can be obtained through regular calibration or online calibration, and is the preferred flowmeter in trade settlement.

3. ZNLWGY high-pressure turbine flowmeter outputs pulse frequency signals, suitable for total measurement and connection with computers, with no zero drift and strong anti-interference ability.

4. The ZNLWGY high-pressure turbine flowmeter can obtain high frequency signals (3-4kHz) with strong signal resolution and operation.

5. The ZNLWGY high-pressure

turbine flowmeter has a wide range, with a medium to large diameter of up to 1:20 and a small diameter of 1:10.

6. The ZNLWGY high-pressure turbine flowmeter has a compact and lightweight structure, easy installation and maintenance, and high flow capacity. Reference source: Baidu Baike - High pressure turbine flowmeter

2. What is the pulse signal output by the turbine flowmeter?? It doesnt have to go through an amplification circuit to amplify and shape it The output of the turbine flowmeter is a pulse signal whose frequency is proportional to the turbine speed, that is, proportional to the flow rate. As long as the flow rate is stable, a stable square wave pulse signal can be output. However, when inputting it into the measurement circuit, considering external interference, signal level matching, and whether the rising and falling edges are fast enough for the digital circuit used for measurement, it is recommended to add a dead start circuit. If the levels match, a Schmitt trigger is generally used.

3. How to measure current with a turbine flowmeter

The turbine flowmeter itself does not directly measure current, but can determine the system status by measuring the 4-20mA signal it outputs.
