Why Choose Us

Installation Instructions

1. When using a vortex flowmeter to measure steam, the body and pipe must be insulated, the flange must be clamped, and there must be no air leakage, otherwise the instrument is easy to damage;
2. It is better to install the instrument indoors, away from vibration and strong electromagnetic interference. If outdoors, the watch head can be protected;
3. The instrument should have 10-15 times the straight pipe section, and then have more than 5 times the straight pipe section. Select the installation place to facilitate installation, wiring and debugging;
4. For a straight pipe section, weld the two flanges before installation, then install the instrument and clamp it, cut off the equal length straight pipe, and then install the whole table welded before. Never weld the watch on the flange.

Model Selection

Selection Directions:

1. Measuring medium: Vortex flowmeter is a speed flowmeter, its principle, determines its measuring medium type, can be liquid, can also be gas or steam;

2. Pipe diameter: Flange connected vortex flowmeter can be divided into pipe type and insert type installation according to the different installation methods;

3. Measurement accuracy: The accuracy of the flange connected vortex flowmeter also has several grades, and it is divided according to the measurement medium. If it is to measure liquid, the measurement accuracy can reach 1.0%, and if it is to measure gas, the accuracy can reach 1.5%. If it is inserted vortex flowmeter, the accuracy can reach level 1.5% and 2.5%;

4. Medium temperature: Generally speaking, it is divided into three ranges, which are divided into normal temperature, medium and high temperature;

5. Nominal pressure: mainly divided according to the installation method, the main demand on the market is as follows: for example, flange clamp type (2.5MPa), flange connection type (1.0/1.6/2.5MPa), plug-in installation type (1.6MPa/2.5MPa/4.0MPa);
