The design principle of LMTK balance flowmeter is based on Bernoulli's law of conservation of energy, using a specially optimized porous disk throttling rectifier sensor (balance flow sensor)
The advantages of LMTK balanced flowmeter:
● High measurement accuracy
The uncertainty of the outflow coefficient in instrument design is ± 0.5%
DN15~500 instrument calibration before leaving the factory
Commissioned third-party calibration for DN500 and above
Low requirements for straight pipe sections
The optimal configuration is 5D in the front and 5D in the back
Normal configuration with 2D before and 2D after
0.5D before and 0.5D after the minimum configuration
Low permanent pressure loss
The maximum permanent pressure loss is about 1/3 to 1/4 of the maximum differential pressure, with low flow noise and fast pressure recovery.
● Wide range ratio
The normal range ratio for use is 10:1
The maximum usage range ratio is 15~25:1
Note: The maximum usage depends on the working conditions and the differential pressure gauge used in conjunction
Good repeatability and long-term stability
Instrument repeatability ≤ 0.1%
Right angle and through-hole design, wear-resistant
The flow field distribution is uniform, and the deviation of the outflow coefficient is small after long-term use
● Resistant to dirt and easy to block
Reduced the formation of eddy currents and dead zones, allowing dirty media to pass through the throttle hole,
Reduce the impact of the accumulation of dirty media on flow measurement
● Wide applicability
The β value can be selected from 0.25 to 0.90
Reynolds number 200-107
Size DN15-3000
Almost all working conditions
Low temperature fluids and liquid gases
Can directly measure bidirectional flow
● Can be used for bidirectional measurement
The throttling element is designed as a symmetrical structure with flat, plate, and straight through holes, and the pressure tapping hole is located at the flange pressure tapping position. With the corresponding differential pressure gauge, it can achieve bidirectional flow measurement with one flowmeter without changing the installation method.
● Easy to install, use, and maintain
The LMTK balanced flowmeter is a differential pressure flowmeter, and its installation, use, and maintenance are completely consistent with standard throttling devices (orifice plate, nozzle, and Venturi).
● Powerful selection calculation software and physical property database
The perfect combination of ISO5167 flow equation and powerful physical property database.
The software's built-in physical property database contains over 1700 types of media, covering almost all measurable media in the chemical industry.
