SYTF-LWGY liquid flow meter sensor

1. Overview of SYTF-LWGY liquid flow meter sensor

SYTFLWGY liquid flow meter sensor is a precision measuring instrument, using advanced micro-processing technology, with strong functions, wide flow range, simple operation, easy to install and use. It is widely used in the measurement of petroleum, chemical industry, metallurgy, scientific research and other fields, and liquid flowmeter sensors equipped with sanitary joints are mostly used in the pharmaceutical field. The products have the following advantages:

1. The pressure loss is small, and the impeller has anti-corrosion function

2. It can be displayed on the spot, instantaneous flow, cumulative total

3. The power of the whole machine is low, and it can work for a long time with the internal battery. It is an ideal passive display instrument

4. Use EEPROM to protect the cumulative flow meter coefficient from power failure, and the protection time is more than 10 years

2. Structure and working principle of SYTF-LWGY liquid flow meter sensor

2.1 Structure

The structure of the sensor is shown in Figure 1. It is mainly composed of a housing, a front guide frame, an impeller, a rear guide frame, a compression ring and a magneto-induction converter with amplifier.

2.2 Working principle

When the measured fluid flows through the sensor, the impeller in the sensor rotates by the kinetic energy of the fluid, and the impeller periodically changes the magnetoresistance in the magnetoelectric induction system. The magnetic flux passing through the coil periodically changes to generate an electrical pulse signal, which is amplified by an amplifier and sent to the corresponding flow totalizer to measure the flow or total volume.
