2012-1-18 10:58:58

主要用于各种行业工业管道中大口径气体、液体、蒸汽介质流体的流量测量,插入式涡街流量计特点是压力损失小,量程范围大,精度高,在测量工况 Plug-in vortex flowmeters are mainly used to measure the flow of large-caliber gas, liquid, and steam medium fluids in industrial pipelines in various industries.The characteristics of plug-in vortex flowmeters are small pressure loss, large measuring range and high accuracy. condition

The volume flow rate is hardly affected by parameters such as fluid density, pressure, temperature, and viscosity. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. Plug-in vortex flowmeter uses piezoelectric stress type transmission

Sensor, high reliability, can work in the working temperature range of -20 ℃ ~ +250 ℃. It has analog standard signal and digital pulse signal output. It is easy to be used with digital systems such as computers. It is a relatively advanced and ideal flow meter. .

The plug-in vortex flow sensor can be widely used for measuring large-caliber gas, liquid, and steam flow meters in various industries, and can also measure turbid liquids containing small particles and impurities, and can be used as a flow transmitter in automatic control systems.

The plug-in vortex flow sensor is explosion-proof type, which complies with the relevant provisions of GB3836-83 "Explosion-proof Electrical Equipment for Explosive Environments". The explosion-proof mark is "iaⅡCT6".

防爆型,符合GB3836-83《爆炸性环境用防爆电气设备》的有关规定,防爆标志为ExdIIBT6。 The plug-in vortex flowmeter is explosion-proof type, which complies with the relevant provisions of GB3836-83 "Explosion-proof electrical equipment for explosive environments", and the explosion-proof mark is ExdIIBT6.

working principle


According to the International Organization for Standardization IS07145 (Determination of fluid flow in a closed section of a circular pipe—speed measurement at one point of the section), a vortex street speed probe embedded in a piezoelectric crystal is inserted into a large-diameter industrial pipe, and the Carmen is rotated.

The eddy frequency is converted into a current or voltage pulse signal or a 4-20mADC current signal that is proportional to the flow rate.


Instrument Features


1, can measure the volume flow and mass flow of steam, gas, liquid;

2. No mechanical moving parts, high measurement accuracy, compact structure and easy maintenance;


3. Low pressure loss and wide measuring range; the range is up to 1:25;

4. Adopt interference cancellation circuit and anti-vibration sensor head;

5. The anti-vibration circuit and anti-vibration sensor are used to make the instrument have certain anti-vibration performance.


6. The measurable medium temperature reaches + 250 ℃.


7, can realize continuous flow disassembly sensor, can achieve amplifier and sensor separation (separation distance 15m);
