KH/LUGB Vortex Flow Meter/Air Flow Meter Price

Air flow meter price

KH-LUGB air flow meterAir flow meter priceIts characteristics are small pressure loss, large measurement range, high accuracy, and it is 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. This instrument uses piezoelectric stress sensors with high reliability and can operate within a temperature range of -20 ℃ to+350 ℃. 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 flowmeterVortex flowmeter/air flowmeter prices.

The pulse frequency signal output by the integrated flow meter VSF is not affected by fluid properties and composition changes, that is, the instrument coefficient is only related to the shape and size of the vortex generator and pipeline within a certain Reynolds number range. However, as a flowmeter in material balance and energy measurement, it is necessary to detect mass flow rate. At this time, the output signal of the flowmeter should simultaneously monitor volume flow rate and fluid density. Fluid properties and components still have a direct impact on flow measurement.

This flowmeter is a new type of flowmeter used for measuring fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of liquefied gas, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure standard volumetric flow rate and mass flow rate, making it an ideal alternative to throttling flow meters.

To improve the high temperature resistance and vibration resistance of the flowmeter, our company has recently developed the Lugb improved flow sensor. Due to its structure and material selection, the sensor can be used in harsh working conditions such as high temperature (350 ℃) and strong vibration (≤ 1g).

In practical applications, large flow rates are often much lower than the upper limit value of the instrument, and with changes in load, small flow rates often fall below the lower limit value of the instrument. To solve this problem, it is usually necessary to reduce the diameter at the measuring point to increase the flow velocity at the measuring point, and use smaller diameter instruments to facilitate the measurement of the instrument. However, this variable diameter method requires a straight pipe section of at least 15D in length between the variable diameter pipe and the instrument for rectification, making processing and installation inconvenient. Our company has developed an LGZ variable diameter rectifier with a curved longitudinal section, which has multiple functions such as rectification, increasing flow velocity, and changing flow velocity distribution. Its structural size is small, only one-third of the inner diameter of the process pipe, and it is integrated with the flow meter. It not only does not require an additional straight pipe section, but also reduces the requirements for the straight pipe section of the process pipe, making installation very convenient.

For the convenience of use, the locally displayed flow meter powered by batteries adopts micro power consumption high-tech. It can operate continuously for more than a year using lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The production selection of temperature compensated integrated industrial sludge flowmeter also includes a temperature sensor, which can directly measure the temperature of saturated liquefied gas and calculate the pressure, thereby displaying the mass flow rate of saturated liquefied gas. The temperature pressure compensation integrated type is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard volume flow rate of the gas.
