The installation method of the barometric flowmeter

The bar flow meter is composed of a detection rod and a pressure taking port. It crosses the pipeline to the vertical of the pipe and the central tube axis, and a detection hole is arranged on the detection surface of the detection rod and the back flow surface of the detection rod, respectively. Pressure tube and static pressure pressure tube lead out, according to the total pressure and static pressure differential pressure value, calculate the flow through the pipe.

1, before the installation of Pakistani flowmeter, the pipeline should be cleaned. When the measured media is unclean, add a filter. Otherwise, the turbine and bearing are easily stuck and no flow can be measured.

2. When disassembling the flowmeter, the magnetic induction part cannot collide.

3. Set the meter factor before putting it into operation. Carefully check to make sure that the instrument wiring is correct and the grounding is good before sending power.

4. When installing the bar flow meter , the front and rear pipe flanges should be horizontal, otherwise the pipe stress has a great influence on the flow meter.

5, the flow meter body selection area with 316 stainless steel materials to prevent corrosion, if the explosion-proof zone must also be explosion-proof results.

6, the bearing is generally carbonized tungsten, PTFE, carbon graphite three specifications: tungsten carbide, high precision, it as a standard industrial control; PTFE, carbon graphite can be anti-corrosion, generally in chemical industry places priority. The square of the bearing life flow rate is positive and negative, so the good flow rate is good at 1/3 of the large flow rate.

7. The sensing probe detects the movement of the rotating body and converts it into a pulsed digital electrical signal. Its output voltage of the electromagnetic coil is close to the sinusoidal curve. The frequency range of the pulse signal changes linearly with the measured flow rate. The typical range is 10: 1,25:1 and 100:1 three specifications. The resistance of the solenoid coil is generally less than 2000Ω, which may be damaged if larger than this value.
