Good price and quality vortex street flowmeter china is mainly used for measuring liquid and gas flow in various industries. The good price and quality vortex street flowmeter china is characterized by small pressure loss, large range and high precision. When measuring the volume flow under working conditions, it is almost not affected by the parameters such as fluid density, pressure, temperature and viscosity, and has no movable mechanical parts. Therefore, it has high reliability and small maintenance. The instrument parameters can be stable for a long time. The plug-in vortex street flowmeter adopts piezoelectric stress sensor, which has high reliability and can work within the temperature range of working liquid flow sensor of - 20 ℃ ~ + 250 ℃. It has analog standard signal and digital pulse signal output, which is easy to be used together with digital systems such as computers. It is an advanced and ideal flow instrument of liquid flow sensor.

1. Good price and quality vortex street flowmeter china is a kind of measuring instrument with high measurement accuracy, simple installation, small maintenance and wide application. It is used in petrochemical, gold treatment, textile, urban construction, energy and other industries.

2. The sensor of good price and quality vortex street flowmeter china outputs frequency signal. It usually forms a flow measurement system with computer or flow integrator.

3. The transmitter of the good price and quality vortex street flowmeter outputs a 4-20mA standard signal proportional to the vortex street flowmeter. It usually forms a flow measurement system with a computer or other flow integrating instruments to form a pipeline vortex street flowmeter.

4. The sensor / transmitter of good price and quality vortex street flowmeter china is installed on the pipeline, and the flow totalizer or computer is installed in the control room and provides power to the good price and quality vortex flow sensor / transmitter. The two are connected by shielded cable.

5. The circuit part of the split pipeline vortex street flowmeter china is separated from the table body. The circuit part is installed in a position with good environment and convenient detection, and it has been connected with the table body with a special cable ≤ 10m when leaving the factory.

Installation requirements of good price and quality vortex street flowmeter china

The good price and quality vortex street flowmeter china is equipped with another pair of standard flanges welded on the front and rear pipes. Welding with flowmeter is not allowed! Before installation, the welding slag and other dirt in the pipeline shall be strictly removed, so that the equal diameter pipeline (or bypass pipe) can be used to replace the flowmeter to purge the pipeline. To ensure that the flowmeter is not damaged during use. When installing the flow meter, the sealing gasket between flanges shall not be concave into the pipe.

Grounding requirements of good price and quality vortex street flowmeter china: the flowmeter shall be reliably grounded and cannot be shared with the grounding wire of strong current system. Requirements for explosion-proof products: for the safe and normal use of the instrument, the use environment of the explosion-proof flowmeter shall be rechecked to see whether it is consistent with the user's explosion-proof requirements. In the process of installation and use, the use requirements of the national explosion-proof products shall be strictly observed. The user shall not change the connection mode of the explosion-proof system or open the instrument at will. The selection shall be within the specified flow range to prevent overspeed operation, so as to ensure ideal accuracy and normal service life.

Before the installation of good price and quality vortex street flowmeter china, the sundries in the pipeline shall be cleaned: debris, welding slag, stones, dust, etc. it is recommended to install a filter with 5 micron sieve at the upstream to block droplets and sand particles. When the flowmeter is put into operation, slowly open the front valve first and then the rear valve to prevent damage to the turbine due to instantaneous air flow impact. The lubricating oil shall be added according to the notice board, and the number of times of refueling depends on the cleanliness of the temperament, usually 2-3 times a year. Overspeed operation of the turbine caused by pressure test, purging pipeline or exhaust, and operation of the turbine in reverse flow may damage the flowmeter. During the operation of the flowmeter, it is not allowed to open the front and back cover at will and change the internal relevant parameters, otherwise the normal operation of the flowmeter will be affected. Carefully install the gasket to ensure that no protrusions enter the pipe to prevent interference with normal flow measurement. When the flowmeter is calibrated, the pressure shall be collected on the pressure tap of the flowmeter.
