In a steam Flow Meter, the magnitude of the disturbance signal determines the lower limit of the steam flow meter range. If you want to extend the lower limit of the range measurement of the steam flow meter, you must reduce the measurement interference signal. The anti-jamming technology of the steam flow meter is introduced below: The anti-interference technology of the steam flow meter In the steam flow meter, the size of the interference signal determines the lower limit of the steam flow meter range. If you want to extend the lower limit of the range measurement of the steam flow meter, you must reduce the measurement interference signal. The following describes the anti-interference technology of the steam flow meter:
PVDF is short for Polyvinylidene Fluoride, it is a kind of Fluoride plastic with excellent physical mechanical and chemical properties, PVDF chemical stability make it no reaction with other substances, in this case it have excellent corrossion resist property and can be used for strong acid. In this case PVDF Diaphragm Valve is most suitable for chemical industrial, semi conduct industria. The working temperature could up to 140 degree. Standard fit for ANSI, JIS, DIN, pressure rate PN10 bar. Manual operate and pneumatic actuator operation both avaliable.
Ningbo RMI Plastic Co.,Ltd offer PVDF diaphragm valve with specification:
Size range:DN15~DN250 (1/2 inch ~ 10 inch)
The interference signals of steam flowmeters mainly include electromagnetic interference and mechanical vibration interference. How to solve the anti-interference signal is the key problem of improving the steam flowmeter. Usually, the steam flow meter is made of a metal casing, and the casing has a good shielding effect, which can effectively prevent electric field and radio frequency interference. The interference with the magnetic field can be solved by replacing the non-magnetic components and the reasonable wiring of the printed circuit board in the internal circuit design of the measuring instrument. However, with the development and improvement of electronic technology, anti-electromagnetic interference is mainly resistant to ground current interference.
In the measurement of steam flowmeter, the main interference factors are electromagnetic interference and mechanical vibration. These two kinds of disturbances limit the range and seriously affect the application of steam flowmeter in the measurement of low flow rate and small flow. It can be anti-interference by using optical isolation current limiting on the circuit. This method can also effectively solve the ground current interference.
