Flange type plastic pipe flowmeter

Overview.

Panel (pipe) type flowmeter is also a float (or float) flowmeter, measuring tube selection of high-quality transparent organic glass. Mainly used in water purification treatment and environmental protection engineering support, can also be used in chemical, petroleum, light industry, medicine, fertilizer, food, paper and scientific research departments, used to measure the flow of liquid single-phase non-pulsating.

Panel pipe type flowmeter has the characteristics of high transparency, intuitive reading, not easy to break, light weight, long life, easy installation and connection.

◆Product implementation standard: Q/YHC.0101-2013 (enterprise standard)

◆Plastic tube flowmeter flange standard: HGT21561-94 (Ministry of Chemical Industry standards)

Installation and precautions.

1. Before installation, the flowmeter export receiver should be taken apart to remove the foam or plastic pipe support inside the instrument, and then reinstall the receiver on, pay attention to the "O" seal should be installed in the receiver groove when reinstalled to prevent water leakage.

2. flowmeter interface available matching plastic pipe (UPVC), with special glue bonding connection. Can also be connected with the plastic flange first, and then connected with the metal flange.

3. The flowmeter must be installed vertically (the angle between the center of the flowmeter and the plumb line does not exceed 5), the installation height should be easy to read the float, read the line of sight should be level with the float reading position.

4. flowmeter upstream and downstream import and export of straight pipe section should be ≥ 5 times the nominal diameter of the instrument.

5. Such as the measured fluid contains larger particles of impurities or spoils, should be installed in the flowmeter upstream filter.

6. Such as the measured fluid is pulsating flow, resulting in float fluctuations can not be measured properly, the flowmeter upstream should be set up the appropriate size of the buffer and the fixed value.

7. Try to use the flowmeter good flow section test flow (good flow section is generally 40%-70% of the larger flow).
