Insertion type plastic pipe flowmeter (short pipe with 304 guide rod)

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).

涡街流量计在工业行业的运用一、涡街流量计介绍达芬奇（1452年-1519年）关键因画家而闻名全球，但他们的奉献不仅仅在于艺术，做为PO峡谷水路的工程师，他研究了例如桥柱和不同种类的漩涡等诸多阻碍物周边的流量，设法对水的习性进行分析并对河流里的流量及其涡旋产生进行了研究，在1513年他第 一次记录了涡旋的行为，同过纪录并归类描述了各种液体流动，达芬奇发现了一种应用图型来描述例如渗流等繁杂自然想像的，并为后代记录了下来。

在1912年西奥多-冯-伦尼变成了测算出涡街流量计工艺的第 一人，为今天的涡街流量计测量技术奠定了基础，在1970年，第 一台用以工业的涡街流量计上市，即测量感应器，当今涡街流量计是规范的测量设备，已普遍用以测量液态，气体和蒸气的流量。
