Product Specification

                                            Intelligent Vortex Flow Meter With 15mm - 300mm Pipe Size 24VDC / 12VDC
 
1. Introduction
LUGBML series Vortex Flow Meter sensor can be used to detect and measure the flow of all kinds of gas, liquid and steam.
LUGBML series Vortex Flow Meter can be used to match with our company’s ML6000 series Velocity Flowmeter. It can also match with a computer and sensors of temperature, pressure, or density to compose high accuracy mass flow or heat flow detecting and measuring system.
 
2. Features

• The structure of Vortex Flow Meter is simple and solid, no movable parts and it is very stable.
• Simple installation and easy maintenance.
• Wide measuring range, the ratio is up to 10:1.
• The volume of fluid is compensated according to requirements, and the instrument coefficient does not need to be re-calibrated after the replacement of the accessories.

3. Working Principle

The vortex flowmeter is a volume flowmeter which measures the volume flow of gas, steam or liquid, the volume flow or mass flow of gas, steam or liquid according to the Karman vortex street principle.

It is mainly used to measure the flow rate of medium fluid in industrial pipeline, such as gas, liquid, steam and so on.

It is characterized by small pressure loss, wide measuring range and high precision, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions.

There are no movable mechanical parts, so the reliability is high and the maintenance quantity is small.

The instrument parameters can be stable for a long time.

The vortex Flowmeter adopts piezoelectric stress sensor with high reliability and can work in the working temperature range of-20 ℃ ~ + 250 ℃.

There are both analog standard signal and digital pulse signal output, which is easy to be used with computers and other digital systems, so it is a relatively advanced and ideal measuring instrument.

6. Design & Installation
 

It is very important to install the instrument, if not properly installed, it will affect the accuracy, service life and damage.

1. In order to avoid switch sets with strong power, high frequency and high power, the meter power supply should be kept away from these devices.

2. Avoid high temperature and radiation sources. If installation is required, take heat insulation ventilation measures.

3. In order to avoid high temperature and enchanted gas, ventilation measures should be taken if installation is required.

4. Vortex flowmeter should not be installed on the part of pipe shaking. If it must be installed on it, a clamping device and a vibration pad located in 2D should be added to enhance the shock resistance. It is better for the instrument to be installed indoors and outdoors, and pay attention to water proof. Pay special attention to the joints, make the cable lead u-shaped, so as to avoid water entering the amplifier body. Enough space should be saved at the installation place to facilitate the installation of the connection line and daily maintenance.
