Precautions for installing vortex flowmeters

The vortex flowmeter is a new type of flowmeter for the measurement of the closed pipe fluid flow based on the Karmen vortex principle. Because of its good media adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. With temperature and pressure sensors, it can measure standard volume flow and mass flow, which is throttling. Ideal alternative to flowmeters.


1. The vortex flowmeter pipeline adopts vibration reduction measures.
The sensor should not be installed on the vibrating pipeline as much as possible, especially the lateral vibration. If it is necessary to install, vibration reduction measures must be taken. Pipe fastening devices are installed at the upstream and downstream 2D ​​of the sensor, and anti-vibration pads are added.
2, vortex flowmeter reasonable choice of installation site and environment.
Avoid strong power equipment, high-frequency equipment, strong power switch equipment; avoid the influence of high-temperature heat sources and radiation sources, avoid strong vibration sites and strong corrosion environment, etc., at the same time to consider the ease of installation and maintenance.
3, vortex flowmeter installed in the horizontal pipeline is the most commonly used flow sensor installation.
When measuring gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed in the higher part of the pipeline.
4, vortex flowmeter sensor installed in the side of the horizontal pipe.
No matter what kind of fluid is measured, the sensor can be mounted on the side of a horizontal pipeline, in particular measuring superheated steam, saturated steam and cryogenic liquids. If conditions permit, side-loading is used, so that the temperature of the fluid has little effect on the amplifier.
5, vortex flowmeter sensor installed in the vertical pipe.
When measuring gas flow, the sensor can be mounted on a vertical pipe with unlimited flow. If the gas to be measured contains a small amount of liquid, the gas flow should be directed upwards.
When measuring the liquid flow, the flow direction of the liquid should be from bottom to top: this will not add extra weight to the probe.
