HLUG series integrated vortex flowmeter with temperature and pressure compensation is mainly used for flow measurement of industrial pipeline media, such as gas, liquid, steam and other media. The integrated vortex flowmeter is characterized by small pressure loss, large range of measurement and high accuracy, and is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow in working conditions. No moving mechanical parts, so high reliability, small maintenance. Instrument parameters can be stable for a long time. The integrated vortex flowmeter adopts piezoelectric stress sensor with high reliability and can work in the operating temperature range of -20℃ ~ +250℃. There are analog standard signal, there are also digital pulse signal output, easy to use with computer and other digital systems, is a more advanced, ideal flow. The pulse frequency signal output by the integrated vortex flowmeter VSF is not affected by the physical property and component change of the fluid, that is, the meter coefficient is only related to the shape and size of the vortex generator and pipeline in a certain Reynolds number range. However, as a flowmeter, mass flow rate should be detected in material balance and energy measurement. In this case, the output signal of the flowmeter should be simultaneously monitored for volume flow rate and fluid density. The physical properties and components of the fluid have a direct impact on the flow measurement. The vortex flowmeter is a new type of flowmeter which can measure the fluid flow in closed pipeline according to the principle of karman vortex. Because of its good medium adaptability, it can directly measure the volume flow of steam, air, gas, water and liquid under working conditions without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volume flow and mass flow under standard conditions, making it an ideal substitute for throttling flowmeter. In order to improve the high temperature resistance and vibration resistance of the vortex flowmeter, our company has recently developed an improved HLUG vortex flow sensor. Due to its * special structure and material selection, the sensor can be used under severe conditions of high temperature (350℃) and strong vibration (≤1g). In practical application, often * a lot far below the threshold value, as the change of load, * small flow and tend to be lower than the lower limit value, instrument is not working in its better section, in order to solve this problem, usually used in the measurement of reducing, improve the measurement of flow velocity and select the * for measuring instrument, but this way of variable diameter in variable diameter pipe between the instrument and the length of the straight pipe for more than 15 d for rectification, processing, installation is inconvenient. Developed by our company profile shape of circular arc LGZ variable diameter rectifier, a rectifier, improve the velocity and change the velocity distribution of multiple function, its structure size is small, just as the process pipe inner 1/3, and the vortex street flowmeter into an organic whole, not only does not need to be added a straight pipe, and can also reduce the requirement for process straight section of pipe installation is very convenient. In order to facilitate the use of the integrated vortex flowmeter, the local display vortex flowmeter powered by the battery adopts the high-tech of micro-power consumption. The local display vortex flowmeter is powered by lithium battery and can run continuously for more than one year, which saves the cost of purchasing and installing the cable and display instrument, and can display the instantaneous flow and accumulated flow on the spot. The temperature compensation vortex flowmeter also has a temperature sensor that can directly measure the temperature of saturated steam and calculate the pressure, thus showing the mass flow of saturated steam. The temperature-pressure compensation system is equipped with temperature and pressure sensors for gas flow measurement, which can directly measure the temperature and pressure of the gas medium, thus showing the standard volume flow of the gas. ◆ measuring medium: gas, liquid and steam; ◆ diameter: flange card-mounted caliber: choose 25,32,50,80,100; flange connection caliber: choose 100,150,200; flow measurement range: normal measurement flow rate range: Reynolds number: 1.5×104 ~ 4×106; Gas 5 ~ 50m/s; The measurement range of liquid and gas flow is shown in table 2.
