Aluminum casting LUX-65 spiral vortex flowmeter

Description :

　　Aluminum casting LUX-65 spiral vortex flowmeter

　　This product is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields, especially suitable for measuring natural gas, dry coal gas, compressed air, etc.

　　1、 Structure:

　　The spiral vortex flowmeter has a compact structure and is mainly composed of a housing, a vortex generator, sensors (temperature, pressure, flow rate), a rectifier, a bracket, and a converter.

　　2、 Characteristics:

　　1. Built in pressure, temperature, and flow sensors with high safety performance, compact structure, and beautiful appearance.

　　2. Display temperature, pressure, instantaneous flow rate, and cumulative flow rate on site.

　　3. By adopting a new type of signal processing amplifier and unique filtering technology, the interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference ability of the flowmeter and ensuring excellent stability for small flow rates.

　　4. The anti-theft function is reliable, with password protection to prevent parameter changes.

　　5. The header can rotate 180 degrees freely, making installation convenient.

　　4、 Installation:

　　1. Operators should be familiar with the working principle, performance characteristics, detection points, and detection items of the vortex flowmeter.

　　2. The operator of the vortex flowmeter prints production and monitoring reports at regular intervals every day to timely reflect the production and operation situation in the factory.

　　3. Regularly conduct on-site inspections of the vortex flowmeter at each testing point and keep records. Any abnormal situations should be promptly handled and reported.

　　4. During rainy weather, check the vortex flowmeter on site, and operators should be careful to prevent electric shock.

　　5. All types of primary sensors for detecting spiral flow meters should be cleaned and scaled as required.

　　6. If there is a malfunction in the vortex flowmeter, do not disassemble the transmitter and converter at will.

　　7. During maintenance and inspection of the vortex flowmeter, protective measures should be taken. Various types of vortex flowmeters that have not been used for a long time or have been soaked in water due to improper use should be dried before use.
