The essence of natural gas flowmeters offer KH-LUGB is characterized by low pressure loss, large measuring range, high accuracy when measuring actual volume flow is almost unaffected by the fluid density, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and low maintenance. Long-term stability of the instrument parameters. This instrument uses piezoelectric stress sensors, high reliability, can work within the operating temperature range of -20 ℃ ~ + 350 ℃ for. Standard analog signals, digital pulse signal output, easy and supporting the use of computers and other digital systems, is a more advanced and ideal flow meter. Pulse frequency signal integrated VSF flowmeter output is not affected by changes in fluid properties and composition, that is only a meter factor and the shape and size of the body, such as pipes and vortex Reynolds number in a certain range of related. But as a flow meter in the material balance and energy to be detected in the mass flow measurement, the output signal then the meter should also monitor the volume flow and fluid density, fluid properties and composition still have a direct impact on the flow measurement. The Karman vortex flowmeter is based on the principle of fluid flow in closed conduits new flow meter measurement. Because it has a good ability to adapt to the medium, no direct measurement of temperature and pressure compensation to gas, air, gas, water, liquid volume flow conditions, with a temperature and pressure sensor measures the standard volumetric flow and mass flow, is the section flowmeter ideal alternative flow. In order to improve the performance of high temperature and vibration meter, the company recently developed a lugb improved flow sensor, because of its unique structure and selection of materials at high temperatures so that the sensor (350 ℃), strong vibration (≤1g) bad use conditions. In practice, often the maximum flow rate is far below the upper limit of the instrument, as the load changes, the minimum flow rate is often lower than the lower limit of the instrument, the instrument does not work at its optimum operating segment, in order to solve this One problem, usually in the measurement of the necking at increasing the flow rate measurement, and use a smaller diameter instrument to facilitate the measurement instrument, but this way there must be adjustable over a length of 15D straight pipe between adjustable and instrumentation rectified pipe sections, the processing, installation is not easy. Our company has developed the profile shape of the arc LGZ adjustable rectifier, a rectifier, increase the flow rate and velocity distribution of the multiple roles change, the structure of small size, only 1/3 of the process pipe diameter, and made one meter, not only No additional attach a straight pipe, can also reduce the requirements for the process pipe straight pipe, the installation is very easy. For ease of use, battery-powered local display type flowmeter micro-power high-tech, using lithium battery can run more than one year without interruption, saving cable and display instruments of procurement and installation costs may display the instantaneous flow, cumulative flow and so on. Temperature compensation integrated industrial sludge production flowmeter selection also has a temperature sensor that can directly measure the saturation temperature of the liquefied gas and calculate the pressure to display saturation liquefied gas mass flow. Temperature and pressure compensation integrated with temperature and pressure sensors, flow measurement may be used to directly measure the gas temperature and pressure of the gaseous medium, thereby displaying standard conditions of gas volume flow. Features low-power CPU central processor and LCD, low power consumption. Easy installation, maintenance is very convenient, long test period, usually two years. Simple solid structure, no moving parts, very reliable long-term operation. Span a wide range: 1:10 normal range, turndown ratio of up to 1:15. Pressure loss, low operating costs, meaning more energy-efficient. Reynolds number in a certain range, the output signal is not affected by the physical properties and composition of the measured medium changes, only the shape and size of the meter factor related to the bluff body, after replacement parts are not normally required to re-calibrate the meter factor. Field display, but also long-distance transmission, but also with computer control system networking. Detection probe is not in direct contact with the measured medium, more stable performance. Temperature and pressure compensation integrated design, the current output are optical isolation, with good resistance to common mode interference suppression.
