XG-LUGB series intelligent vortex flowmeter

The XG-LUGB series vortex flowmeter is a new type of flowmeter developed based on the Karman vortex principle. The vortex flowmeter is suitable for measuring the mass flow rate and volume flow rate of superheated steam, saturated steam, compressed air, general gases, water, and low-corrosive liquids.

Product Features:
1. Low pressure loss, low operating costs, and more energy-saving significance.
2. Simple structure, no movable parts, no wear and tear, no need for mechanical maintenance.
3. The measurement range is wide, up to 10:1 (can be extended for special cases).
4. Adopting a low-power CPU central processing unit and LCD, with a low-power design and low energy consumption, it is divided into a battery-powered local type (battery can last for 2 years) and a battery-powered remote transmission type, as well as an externally powered remote transmission type, with stable and reliable performance.
5. The circuit is highly integrated, technologically advanced, and has no drift or self-excitation. It displays parameters such as temperature, pressure, instantaneous flow rate, cumulative flow rate, density, and frequency on site. Voltage stabilization compensation can be applied to the tested medium.
6. Adopting a hidden button design and password menu management, it effectively prevents unauthorized personnel from modifying the instrument, and the instrument parameters are easily set on site.
7. The instrument is designed with digital pulse output and also has a two-wire 4-20mA current output. With HART protocol. Equipped with an RS485 communication interface.
8. A specific real-time data storage function ensures that internal data is never lost in any situation.
9. Using piezoelectric crystal detection components, it has high reliability and can operate within the range of -20~280 ° C.
10. It has a flange card type, DN25-300; flange insertion type, DN300-2000.
11. Explosion-proof rating: Exd lI BT4.
12. Protection level: IP65.                                                  

Core selling points:
1. Simple and sturdy structure: There are no moving or worn parts inside, with a long service life and low maintenance workload.
2. Wide range: It can measure gases, vapors, and liquids, with a large range ratio and the ability to measure both high and low flow rates.
3. Stable accuracy and adaptability to multiple media: One instrument can measure liquids, gases, and saturated/superheated steam, with strong versatility.
4. Intelligent signal output: Local LCDs instantaneous and cumulative flow rates; Supports 4-20mA, pulse RS485‑Modbus, convenient to connect with the PLC upper system.

Application industry:
1. Thermal heating industry: boiler steam, thermal pipeline steam metering, heating settlement.
2. Petrochemical industry: flow monitoring of process gases and various liquid media.
3. Food and pharmaceutical industry: compressed air, process steam, and production water flow control.
4. Municipal public utilities: Measurement of public energy sources such as compressed air, gas, and circulating water.

FAQ Performance Specifications

Q1: What media can a vortex flowmeter measure?
A: Can measure liquids, gases, saturated vapors, and superheated vapors. Cannot measure media containing a large amount of solid particles and high viscosity that are prone to scaling, which can easily damage the probe and affect measurement.

Q2: What is the reason for the large fluctuation in the flow reading of the vortex flowmeter?
A: The common reasons are low pipeline flow rate, large pipeline vibration, insufficient upstream and downstream straight pipe sections, and the presence of a large number of bubbles in the medium. Prioritize ensuring sufficient front and rear straight pipe sections, avoiding vibration sources such as pumps and valves, and improving working conditions.

Q3: What are the requirements for installing a straight pipe section in a vortex flowmeter?
A: To ensure measurement accuracy, a straight pipe section with a diameter of 15-20 times is generally required upstream, and a straight pipe section with a diameter of 5-10 times is required downstream. Try to stay away from turbulence components such as bends, valves, and pump bodies as much as possible; otherwise, it may cause measurement deviation.

Q4: How to choose between vortex flowmeter and electromagnetic flowmeter?
A: Select a vortex flowmeter for measuring steam, gas, and non-conductive liquids; electromagnetic flowmeters are selected for measuring conductive liquids such as sewage, acid, alkali, and mud media, based on the type of medium being measured.
