High Accuracy Vortex Flow Meter Easy Maintenance M20*1.5 Electrical Connection

                        Vortex Flow Meter for Oil Industry / Chemical Industry / Metallurgy / Heating Power / Paper Making / Spinning
 
1. Introduction
LUGBML is based on Von Karman’s Vortex Principle, which adopts piezoelectric crystal as testing components. It is a new kind of stress detecting vortex flow meter. It has the advantage of wide range ratio, high accuracy, low pressure loss, good medium generality, pulse output proportional to flow, convenient to connect with computer and etc. As the detector probe of sensor and the vortex generating body are installed separately, and the high temperature resistant piezoelectric crystal doesn’t contact with medium, so the instrument is of simple structure, good generality and high stability.
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.

4. Design & Installation

The installation of the instrument is very important, if the installation is not good, it will affect the accuracy, service life and damage.

1. In order to avoid high-power, high-frequency, high-power switch groups, instrument power supplies should be avoided near these devices.

2. Avoid high temperatures and radiation sources. If installation is required, thermal insulation and ventilation measures should be taken.

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

4. The eddy current flowmeter should not be installed in the sloshing part of the pipe. If it must be installed on it, a clamping device and a vibration pad located in 2D should be added to enhance shock resistance. It is best to install the instrument indoors, pay attention to waterproof during outdoor installation, and pay special attention to the joint to make the cable wire U-shaped, so as to prevent water from entering the amplifier body, and enough space should be saved at the installation place for installation and routine maintenance.
