Temperature and Pressure Compensated Vortex Flowmeter: 

Advanced Measurement Solution for Industrial Fluids

The temperature and pressure compensated vortex flowmeter is an advanced instrument for measuring the flow rate of industrial pipeline media fluids. It combines the basic principles of vortex flowmeters with temperature and pressure compensation technology. As a key device for measuring fluid flow, the accuracy of the flowmeter directly affects the control of the production process, the evaluation of resource consumption, and the calculation of economic benefits.

1. Basic principles

The vortex flowmeter is a new type of flowmeter that measures the flow rate of closed pipeline fluids based on the Karman vortex principle. When the fluid flows through the vortex generator of the vortex flowmeter, two regular vortices will be generated alternately on both sides. The release frequency of these vortices is proportional to the average flow rate of the fluid. By measuring the release frequency of the vortex, the flow rate of the fluid can be calculated.

2. Features and advantages

(1) High precision: The temperature and pressure compensated vortex flowmeter can accurately measure the flow rate of the fluid, and eliminate the influence of temperature and pressure changes on the measurement results through temperature and pressure compensation technology, thereby improving the measurement accuracy.

(2) Wide applicability: The flowmeter can be used to measure a variety of media such as gas, liquid, and steam, and has a wide range of applicability.

(3) Good stability: Due to the use of advanced technologies such as piezoelectric stress sensors, the temperature and pressure compensated vortex flowmeter can work stably for a long time and maintain good measurement performance.

(4) Easy maintenance: The flowmeter has no movable mechanical parts, so the maintenance is small and the instrument parameters can be stable for a long time.

(5) Easy to use: The flowmeter has analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers, facilitating automatic control and remote monitoring.

3. Application fields

The temperature and pressure compensated vortex flowmeter is widely used in process measurement and energy-saving management of single-phase fluids such as various liquids, gases, and steam in petrochemical, metallurgical, textile, pharmaceutical, machinery, water supply, heating, thermal power, scientific research and other industries. It plays an important role in industrial process control and energy management and measurement.

4. Technical parameters

The technical parameters of the temperature and pressure compensated vortex flowmeter include the measuring medium (gas, liquid, steam), caliber specifications (such as flange clamp caliber selection 25,32,50,80,100, etc.), flow measurement range (such as normal measurement flow rate range Reynolds number 1.5×104～4×106; gas 5～50m/s; liquid 0.5～7m/s), measured medium temperature (normal temperature –25℃～100℃; high temperature –25℃～150℃ -15℃～300℃，etc.), accuracy level (such as 5.5 level, 1.5 level), etc.

The specific values of these parameters will vary according to different models and specifications.

With the continuous improvement of industrial automation level and the continuous development of measurement technology, the temperature and pressure compensation technology of flowmeter is also constantly improving and improving. In the future, with the integration and application of advanced technologies such as smart sensors, Internet of Things technology, and big data analysis, the temperature and pressure compensation of Qingdao Hesheng Measurement and Control Flowmeter will become more intelligent and precise, providing more efficient and reliable flow measurement solutions for industrial production and energy management.
