Compressed air flow meter

Sino-Inst manufactures compressed air flow meters.

Compressed air flowmeters can be measured with a target type flowmeter, which not only has the characteristics of traditional orifice plates, turbines, vortex streets and other flowmeters without moving parts, but also has a measurement accuracy comparable to that of volumetric flowmeters, plus Its unique anti-interference and anti-impurity performance, in addition to replacing the flow measurement problem that can be measured with conventional flow, especially for small flow, high viscosity, easy to condense, high temperature, strong corrosion, strong vibration, etc. It has good adaptability in working conditions.

Compressed air flow meters have been widely used in flow measurement in metallurgy, petroleum, chemical, energy, food, environmental protection and other fields

1. Measurement medium: gas, liquid, steam.

2.Dual-row LCD displays both cumulative flow and instantaneous flow;

3.Powered by internal lithium battery, no external power required;

4.Micro power design, two + 3v lithium batteries can work continuously for more than one and a half years;

5. The sensing element of the air quality sensor is not in direct contact with the measured medium, and has stable performance and high reliability.

6. There are no moving parts in the sensor, the structure is simple and firm, the pressure loss is small, the dimension expansion is small, and the service life is long.

7. The range is as wide as 10: 1 ~ 15: 1.

8. Measurement range of compressed air flow meter: normal working range, Reynolds number is 20,000-7,000,000; output signal is not affected by liquid temperature, pressure, viscosity and components. Possible measurement range, Reynolds number 8,000-7,000,000.

9, accuracy level: liquid, ± 1.0% of the indicated value; gas, ± 1.0% of the indicated value; steam, ± 1.5% of the indicated value.

10. Output signal: a.oc gate pulse output; b. Current 4-20ma (two-wire system / three-wire system).

11. Power supply voltage: + 24vdc (provided when signal output is required).

12. Medium temperature: common type a. -40 ℃ ～ + 130 ℃; b. -10 ℃ ～ + 250 ℃;

13. Working pressure of compressed air flow meter: 0-2.5mpa, flange clamp connection (Note: other pressure levels can be provided according to user requirements, which need to be customized).

14. Pressure loss: δpδp = 1.079 * 10-6 * ρ * v2 (where: δp: pressure loss kpa; ρ: density of the measured medium kg / m3; v: flow velocity of the measured medium m / s).

15. Housing material: carbon steel; stainless steel (1cr18ni9ti).

16, specifications (inner diameter of the pipeline) 20, 25, 32, 40, 50, 65, 80, 125, 150, 200, 250, 300 (greater than dn300 diameter is plug-in).

17. Ambient temperature -25 ℃ ～ + 55 ℃; humidity ≤85% rh.

18. Explosion-proof type of compressed air flow meter: Explosion-proof type; Explosion-proof mark; iaiict4.
