Steam vortex flowmeter flow fluctuations how to deal with large

Project Overview

Steam vortex flowmeter is a commonly used flowmeter in steam measurement. It is suitable for measuring the volume flow of steam. With auxiliary instruments such as pressure transmitters, temperature sensors, and intelligent flow totalizers, it can accurately calculate Mass flow rate of steam. However, during its long-term use, steam vortex flowmeters may also experience some common failures. Today, we will share with you solutions to problems such as sloshing and large fluctuations in the display value of steam vortex flow meters based on user examples.

Solution:

Steam vortex flowmeter has problems such as shaking and large fluctuations in the indication value, which is usually caused by the presence of bubbles, impurities and other reasons in the fluid medium. To solve this problem, the following measures can be taken:

(1) Check whether there are bubbles, impurities, etc. in the fluid medium. If so, corresponding measures need to be taken to deal with it, such as adding filters, etc.

(2) Check whether the flow meter is firmly installed. If it is loose, it needs to be tightened in time.

(3) Check whether the sensor is damaged. If it is damaged, replace it with a new one.

User case:

A user of a heating company's DN200 steam vortex flowmeter has been measuring normally during use. During subsequent use, it was found that the flow fluctuation was relatively large and the cumulative flow was obviously too large. a lot of. The technicians checked on site that there were no problems with parameter settings, instrument installation, and wiring, and there were no sources of interference on site. The technician determined that there might be foreign matter inside the sensor. After removing the vortex flowmeter for inspection, he found that there was a lot of debris wrapped around the vortex generator (graphite gasket wrapped around metal). After communicating with the user, it should be that the pipe in front of the meter was in use during use. It was caused when replacing the valve. After cleaning, reinstall the vortex flowmeter and the measurement returned to normal.

Steam vortex flow meters will inevitably encounter some common faults during long-term use. After a malfunction occurs, non-professionals should not operate at will and contact the manufacturer's technical personnel as soon as possible. Qingdao Hesheng Measurement and Control has been engaged in the generation, research and development and sales of flow meters for many years. It has a professional after-sales team that responds within 24 hours. It can provide door-to-door guidance services across the country to provide users with timely and effective solutions to improve vortex streets. The use effect of flow meter ensures the accuracy and stability of industrial flow measurement.
