DN100 Spiral Vortex Flow Meter

Description :

　　DN100 Spiral Vortex Flow Meter

　　1、 Overview:

　　The FH-LUX series intelligent vortex gas flowmeter has the advantages of strong functionality, wide flow range, simple operation and maintenance, and easy installation and use.

　　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.

　　3、 Technical parameters:

　　1. The flow range is the flow range verified at the time of product delivery (at room temperature and atmospheric pressure, the medium is air 1.205Kg/m3); As the pressure increases, the flow range also expands.

　　2. Standard state conditions; P=101.325kPa，T=293.15K。

　　3. Usage conditions: Environmental temperature: -30~+60 ℃, medium temperature: -20~+80 ℃, relative temperature: 5%~95%, atmospheric pressure: 86kPa~106kPa.

　　4. Electrical performance indicators

　　Working power supply: external power supply:+24VDC, internal power supply: 3.6V lithium battery, overall energy consumption: external power supply,<1W, internal power supply,<0.3MW, lithium battery can be used for more than two years.

　　Output mode: frequency signal, 4-20mA signal, RS485 communication (capable of transmitting temperature, pressure, instantaneous flow rate, and cumulative flow rate parameters).

　　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;

　　When installing flow meters and measuring pipelines, consideration should be given to installing expansion pipes and corrugated pipes. Based on the actual size of the flow meter, the upstream and downstream pipelines should be laid reasonably to minimize the deformation of the flow meter caused by pipeline stress;

　　7. The casing of the flow meter volume correction device is equipped with grounding screws, which must be reliably grounded according to the specified requirements during use, but must not share the grounding wire with the high-voltage system; When installing or testing on pipelines, it is not allowed to overlap the grounding wire of the welding system with the flow grounding wire;

　　During use, users are not allowed to change the connection method of the explosion-proof system or arbitrarily modify the various lead interfaces. The outer diameter of the incoming cable is 8-8.5mm, and the remaining entry holes should be plugged for sealing.
