Fenghui Instrument LUX Spiral Vortex Flow Meter

Description :

　　Fenghui Instrument LUX Spiral Vortex Flow Meter

　　1、 Overview:

　　This series of products complies with the national enterprise standard JJG198-94 "Verification Regulations for Velocity Flowmeters" Q/320831AHH003-2004 "HLUX Series Intelligent Spiral Gas Flowmeters".

　　This series of products has been verified and approved by the National Instrumentation Explosion Safety Supervision Department (NEPSI), and complies with the relevant provisions of national standards GB3836.1-2010 and GB3836.2-2010. The explosion-proof mark of the explosion-proof type is Exd Ⅱ CT6.

　　2、 Main features:

　　1. The built-in pressure, temperature, and flow sensors have multiple compensation methods for users to choose from, with high safety performance, compact structure, and beautiful appearance.

　　2. On site display of temperature, pressure, instantaneous flow rate, and cumulative total amount.

　　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 making small flow rates have excellent stability.

　　4. The whole machine has extremely low power consumption and can operate for a long time with internal battery power supply, making it an ideal on-site display instrument without the need for external power supply.

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

　　6. Equipped with two-wire and three wire 4-20mA standard current signal output, pulse output, and RS485 interface.

　　4、 Installation:

　　1. There should be no strong external magnetic field interference or strong mechanical vibration around the flowmeter. Before installation, the environmental conditions should be reviewed according to its usage requirements for normal use;

　　When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter;

　　3. The flowmeter can be installed at any angle, and the direction of fluid flow should be consistent with the direction indicated on the housing. There should be straight pipe sections of 10DN and 5DN upstream and downstream of the flowmeter, respectively;

　　4. The flowmeter should be installed coaxially with the pipeline, and the flange screw hole connection should be parallel to the pipeline axis to prevent sealing gaskets and grease from entering the pipeline cavity;

　　5. If necessary, a filter can be installed upstream of the flowmeter to filter out particles and debris in the medium.
