JG-HLUG series with temperature and pressure compensation-in-one flowmeter is mainly used for industrial pipe medium fluid flow measurement, such as gas, liquid, vapor and other media. One type vortex flowmeter is the pressure loss characteristics, scale range, high precision in the measurement conditions are not nearly the volume density of the fluid flow, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and little maintenance. Long-term stability of the instrument parameters. This instrument uses piezoelectric stress sensors, high reliability, can be -20 ¡æ ~ +250 ¡æ operating temperature range. With analog standard signal, but also digital pulse signal output, easily supporting the use of computers and other digital systems is a more advanced and ideal flow¡£
VSF-one vortex flowmeter output pulse frequency signal from fluid properties and composition changes, that instrument coefficient in a certain Reynolds number range, and only with the bluff body shape and size of the pipe and so on. But as the material balance and energy flow in the measurement of mass flow to be detected, then the flow meter should also monitor the volume of the output signal flow and fluid density, fluid properties and composition of the flow measurement or have a direct impact¡£
Karman vortex flowmeter vortex principle is the basis for Measurement of fluid flow in closed conduits new flow meter. Media because of its good ability to adapt, without direct measurement of temperature and pressure compensation can be steam, air, gas, water, liquid volume flow conditions, with temperature and pressure sensor measures the standard volume flow and mass flow conditions, is to cut expenditure Flowmeter ideal alternative¡£
To improve the high temperature vortex flowmeter and anti-vibration performance, the company recently developed a HLUG improved vortex flow sensors, because of its unique structure and selection of materials so that the sensor at high temperature (350 ¡æ), high vibration (& le ; 1g) use of harsh conditions¡£
In practice, the maximum flow rate is often much lower than the upper limit of the instrument, as the load changes, the minimum flow rate and often lower than the lower limit of the instrument, meters are not working in its optimum operating segment, in order to solve this problem , commonly used in the measurement at the reduced diameter to improve the measurement at the flow rate, and smaller-diameter instrument to facilitate selection of the measurement instrument, but this must be adjustable means between adjustable tube and instrument over a length of straight pipe section 15D to Rectifier, the processing, installation is not easy. Our company has developed a vertical section of the shape of arc rectifier LGZ adjustable, with a rectifier to improve the flow and velocity distribution change multiple roles, its structure, small size, process tube diameter of only 1 / 3, one made with the vortex flowmeter Not only do not need to add another section of straight pipe, you can also reduce the process tube straight pipe requirements, installation is easy¡£
For ease of use, battery-powered display-type vortex flowmeter of local micro-power high-tech, using lithium uninterrupted power supply can run more than one year, saving the cable and display instruments for the procurement and installation costs, may show the instantaneous Flow, cumulative flow. Temperature compensation is also a body vortex flowmeter with a temperature sensor, can measure the temperature of saturated steam and calculate the pressure, which shows the mass flow of saturated steam. Temperature and pressure compensation for a body with a temperature and pressure sensors, gas flow measurement can be directly used to measure the temperature and pressure of gas medium, which shows the standard conditions of gas volume flow¡£
