I. Overview
HD-LUGB (L) seriesThe Chinese display of threaded connection vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter. Our company can produce seismic dynamic vortex street flowmeters, which have been widely put into use
Threaded connection vortex flowmeter Chinese display product features
No movable parts, long-term stability, simple structure for easy installation and maintenance
The sensor output is a pulse frequency, which is linear with the actual flow rate of the measured fluid, with zero drift and very stable performance
High precision, typically with a measurement accuracy of ± 1.0% for liquids; The measurement accuracy of gas is ± 1.5%
The measurement range is wide, reaching 1:20 within the Reynolds number range of 2 × 104 to 7 × 106
Low pressure loss (about 1/4 to 1/2 of orifice flowmeter), belonging to energy-saving flow meters
The installation method is flexible, and it can be installed horizontally, vertically, and at different angles according to the on-site process pipeline blockage
Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance
Using ultra-low power single-chip microcomputer technology, one 3V10AH lithium battery can be used for more than 5 years
Correction of instrument coefficient nonlinearity by software to improve measurement accuracy
Using EPROM for power down protection of accumulated traffic, with a protection time greater than 10 years.
2、 Product Features
1. There are no movable parts inside the sensor, and the structure is simple and firm, so the performance is stable and the service life is long 2. The internal design and layout of the sensor are reasonable, resulting in less pressure loss and less maintenance 3. Wide measurement range, up to 15:1 or 20:1 4. Flange clamped or plug-in connection, easy to install and operate 5. Output a pulse signal proportional to the flow rate (or can be converted to 4-20mA), suitable for total quantity measurement, without zero drift 6. Strong universality, can form a measurement and control system with flow integrators produced by Hefei Tongshuo Instrument Technology Co., Ltd. or other manufacturers
