KH-LGB series intelligent vortex flowmeterMainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as liquid density, pressure, and temperature 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.Which is a good exhaust gas flowmeter???? Vortex flowmeter
The major advantage of KH-LGB intelligent vortex flowmeter is its excellent anti vibration performance, no zero drift, and high reliability.
Through extensive waveform and frequency analysis of the vortex flowmeter over a long period of time, Kehao has designed an optimal probe shape, wall thickness, height, probe rod diameter, and matching piezoelectric crystal. Advanced CNC lathes are used for processing to ensure the technical parameters of coaxiality and smoothness, and special processing techniques are used to overcome the common problem of the inherent self oscillation frequency of the vortex flowmeter affecting the signal to the greatest extent possible. This is the technological advantage of Kehao Company in producing vortex flowmeters, which enables the vortex flowmeters produced by Kehao Company to have good anti vibration capabilities.
② The sensor of the LGB series intelligent vortex flowmeter has strong universality, which makes the sensor have good interchangeability. Advanced CNC equipment is used to process the sensor body and vortex generator to ensure processing accuracy, thereby making the components (especially the vortex generator) highly versatile and truly ensuring that the repeatability and accuracy of the sensor will not be affected by component replacement; Capable of generating strong and stable vortex signals.
③ The structure is simple and sturdy, with no movable parts, high reliability, and easy to use and maintain.
④ The detection component does not come into contact with the medium, with stable performance and long service life
The sensor adopts a detection probe installed separately from the vortex generator, and a high-temperature resistant piezoelectric crystal is sealed inside the detection probe, which does not come into contact with the measured medium. Therefore, the FFM63 series vortex flowmeter has the characteristics of simple structure, good universality, and high stability.
⑤ Output pulse signals or analog signals proportional to the flow rate, without zero drift, high accuracy, and convenient networking with computers
⑥ Wide measurement range, with a range ratio of up to 1:10
⑦ When measuring volumetric flow rate with a vortex flowmeter, no compensation is required. The signal output by the vortex flowmeter is actually linearly related to the flow rate, that is, directly proportional to the volumetric flow rate. The purpose of pressure and temperature compensation is to obtain the density of the fluid, which is multiplied by the volumetric flow rate to obtain the mass flow rate. If measuring the volumetric flow rate of a gas, compensation is not required.
⑧ Low pressure loss.Which is a good exhaust gas flowmeter???? Vortex flowmeter
Using a DN50 vortex flowmeter to measure the flow rate of combustible gases, if the large flow rate Qmax in the pipeline is 200m3/h, the pressure loss of the sensor is: △ P=1.08 × 10-6 ρ v2 (kPa)=0.605 KPa
⑨ Within a certain Reynolds number range, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density, or composition, but only by the shape and size of the vortex generator.
⑩ Widely applicable, capable of measuring the flow rates of steam, gas, and liquid.
