Liquid Integrated Vortex Flowmeter with Explosion Proof Made in China

1. Introduction

LUGBML is based on vonkarman's vortex principle and uses pyelectron crystals as a test element. It is a new type of stress detection vortex street flow meter. It has the advantages of large range ratio, high precision, small pressure loss, good media versatility, pulse output and flow ratio, easy to connect with the computer, because the sensor probe and vortex generator are installed separately, high temperature-resistant die-electric crystals do not touch the instrument simple structure, good versatility, high stability. The LUGBML series of vortex street flow meter sensors can be used to detect and measure the flow of a wide range of gases, liquids and vapors. Can be used with my company ML6000 series vortex street flow meters. It can also be combined with computers and temperature, pressure, density sensors to form a high-precision mass flow or heat flow detection system.

2. Features

• The vortex flowmeter has the advantages of simple and solid structure, no moving parts and good stability.
• The utility model has the advantages of simple installation and convenient maintenance.
• The measuring range is wide, with a ratio as high as 10:1.

• The amount of liquid is compensated as required, and there is no need to recalibrate the instrument coefficient after changing the accessories

5. Design & Installation

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

1. In order to avoid high-voltage, high-frequency and high-power switch groups, the instrument power supply should be avoided close to these devices.

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

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

4. Vortex flowmeter should be avoided to be installed in the shaking part of pipeline. If it must be installed on it, the clamping device and vibration pad located in 2D should be added to strengthen the shock resistance. It is best to install the instrument indoors, pay attention to waterproof when installing outdoors, pay special attention to the joint, and make the cable lead into U-shape to avoid water entering the amplifier body. The installation place should save enough space for installation of connecting wires and daily maintenance.
