Vortex Flow Meter with Fluid Temperature up to 350℃ High Temperature
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.

5. 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.
