LUXB-40 LUXB-50 LUXB-65 LUXB-80 Vortex flowmeter

LUXB-40 LUXB-50 LUXB-65 LUXB-80 Vortex procession flow meter

Overview

LUXB-40 LUXB-50 LUXB-65 LUXB-80 Vortex procession flow meter is widely used in various gas metering in petroleum, chemical, electric power, metallurgy, coal and other industries. Vortex procession flow meter used microprocessor technology, which has the advantages of strong function, wide flow range, simple operation and maintenance, convenient installation and use, and its main technical indexes reach the level of similar foreign products.

Working principle of LUXB-40 LUXB-50 LUXB-65 LUXB-80 Vortex procession flow meter

The procession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element measures the fluid secondary rotation procession frequency to obtain good linearity in a wide flow range. The signal is amplified, filtered and shaped by the amplifier and converted into a pulse signal proportional to the flow rate, and then sent to the microprocessor together with the detection signals such as temperature and pressure for integration processing, and finally displayed on the liquid crystal display. Results (instantaneous flow, cumulative flow and temperature, pressure data).The flow profile of the flow sensor resembles the profile of a venture. A set of helical guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent vortex flow. When the fluid enters the diffusion section, the vortex flow is affected by the back-flow and begins to perform secondary rotation, forming a gyroscopic vortex procession phenomenon.

Features of LUXB-40 LUXB-50 LUXB-65 LUXB-80 Vortex procession flow meter

1. Using a new signal processing amplifier and unique filtering technology, the interference signal caused by pressure fluctuation and pipeline vibration is effectively eliminated, which greatly improves the resistance of the flowmeter and makes the small flow have excellent stability.

2. The unique function of time display and real-time data storage, no matter what the situation, can ensure that the internal data will not be lost and can be stored securely.

3. The power consumption of the whole machine is extremely low, and it can be powered by the internal battery*, which is an ideal display instrument on the spot without external power supply.

4. The anti-theft function is reliable, with password protection to prevent parameter changes.

5. The LUXB-40 meter head can be rotated 180 degrees at will, which is easy to install.

6. Built-in pressure, temperature, flow sensors, high safety performance, compact structure, beautiful appearance.

7. In-situ display of temperature, pressure, instantaneous flow and cumulative flow.
