Embellish instrument in the production of turbine flowmeter
with its stable performance and superior quality in the market by the vast number of users, the series of products including the RZ
LWGY used to measure the liquid of turbine flowmeter and RZ -
LWGQ gas turbine flowmeter to measure gas, liquid for gas turbines and turbine flowmeter, because for different gas and liquid medium, the required measurement requirement is different also, gas turbine flowmeter pressure compensation device to increase the temperature, can be accurately measured.
This article will take the liquid turbine flow meter
as an example to illustrate when installation matters needing attention.
LWGY series liquid turbine flowmeter is widely used in measurement in a closed pipe with 1 cr18ni9ti stainless steel, 2 cr13 and corrode corundum AI2O3, cemented carbide, and no fiber, particles and other impurities, motion viscosity temperature less than 5 & times;
6 m2 / s liquid, the kinematic viscosity is greater than 5 & times;
6 m2 / s of the liquid, can be used for solid liquid flow meter calibration after, you can also control quantitatively, excessive alarm, etc. , is an ideal instrument to flow measurement and energy saving.
Key points include: * first, after the liquid turbine flow meter installed, be sure to study serious liquid turbine flow meter specifications.
For the first time in the operation of the problems encountered, to analytical thinking.
Liquid of a complete set of turbine flowmeter is already in the factory flow calibration device to adjust the calibration, check the form a complete set of sensors and switches, as long as the meter coefficient correctly, such as general liquid turbine flow meter without any adjustment can be put into operation.
Second, the instrument before put into operation, liquid turbine flowmeter sensor must be full of actual measured medium, after electrify in the stationary state record of zero adjustment.
Operation should be according to the medium and conditions of use periodically stop check zero flow, especially for easy to precipitate, easy to pollution, the cleaning medium containing solid electrode, at the beginning of the run should be check more, to gain experience, determine the normal inspection cycle.
Third, if the contact resistance of two electrodes changes, shows that liquid turbine flowmeter electrodes are likely to be contamination;
Increasing the contact resistance and may touch dirt is insulation sediment;
Contact resistance becomes possible touchs dirt is the conductivity of the sediment;
Asymmetry of two electrode contact resistance, shows two different electrode contaminated degree;
The electrodes and the excitation coil insulation resistance drop shows liquid turbine flowmeter sensor the degree of be affected with damp be affected with damp;
When insulation resistance drops to a certain extent, will affect the normal work of the instrument.
