 High temperature steam flowmeter

High temperature steam flowmeter

Product Description: Overview of high temperature steam flowmeter products: Vortex street flowmeter is manufactured by Carmen vortex street principle. It has the advantages of high precision, wide measuring range, low power consumption, easy installation, simple operation and small pressure loss. It can measure the volume of work flow or standard volume flow (integrated intelligent temperature and pressure compensation). According to the needs of users, the density, pressure, temperature and viscosity of fluid density are almost independent of the measured volume and flow rate. The influence of other parameters can be attached to pulse or 4 to 20mADC current output function. There are no movable parts, so the reliability is high and the maintenance quantity is small. Using piezoelectric stress sensor, instrument parameters can be stable for a long time. The working principle of the high temperature steam flowmeter is the vortex flowmeter, which is composed of a vortex generating body, a probe and corresponding electronic circuits designed in the flow field. When the fluid flows through the vortex generating body, the two sides of the two sides of the vortex form alternating two rows of vortices, which are called Carmen vortex street. The advantages of vortex flowmeter are 1 and the temperature compensation compensation function is integrated in the body at the same time.

Working principle of high temperature steam flowmeter
Vortex flowmeter is composed of vortex generator, probe and corresponding electronic circuit designed in the flow field. When the fluid flows through the vortex generating body, the two sides of the two sides of the vortex form alternating two rows of vortices, which are called Carmen vortex street.
 
 Advantages of high temperature steam flowmeter
 
Advantages of vortex flowmeter
1. The temperature compensation compensation function is integrated in the body at the same time, which can measure the standard volume flow or standard mass flow rate of the fluid.
2. The fully intelligent and digital circuit design can automatically compensate the measured fluid density or the volume of the standard condition.
3, the new digital filtering and correction function makes the flow measurement more precise and reliable.
4. Battery powered type can operate continuously for more than two years without external power supply.
5. The new dot matrix LCD is easy to use and operate.

Application characteristics of vortex flowmeter for high temperature steam flowmeter
Vortex flowmeter is based on the vortex street principle of Carmen (Karman). It is mainly used for measuring the flow of industrial medium fluid, such as gas, liquid, steam and other media. It is characterized by low pressure loss, wide range and high accuracy. It is almost not affected by parameters such as fluid density, pressure, temperature, viscosity and so on. There are no movable parts, so the reliability is high and the maintenance quantity is small. Instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20 to +250 C. It has analog standard signal and digital pulse signal output. It is easy to use with digital systems such as computers. It is an advanced and ideal measuring instrument.
 
High temperature steam flow meter function:
1. LCD dot matrix Chinese character display is intuitive and convenient, and operation is concise and clear.
2. full function HART protocol, including special commands;
3. interface with temperature / pressure sensor. The temperature can be matched with Pt100 or Pt1000, and the pressure can be connected to the gauge or absolute pressure sensor, and it can be modified piecewise.
4. output signal diversification, according to customer requirements, choose two wire 4-20mA output, three wire pulse output and three wire equivalent output.
5. excellent nonlinear correction function, greatly improving instrument linearity.
6., it has the function of software spectrum analysis, which improves the ability of instrument to resist interference and earthquake.
