Steam flow meterMainly used for flow measurement of steam medium fluid in industrial pipelines, steam vortex flowmeter is characterized by small pressure loss, large range, high accuracy, and is suitable for measurement\\The volumetric flow rate is almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The steam flowmeter adopts a piezoelectric stress sensor, which has high reliability and can operate within the working temperature range of -20 ℃ to+250 ℃. 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 flow meter.

Steam flow meterThe output pulse frequency signal 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. It is a new type of flowmeter 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 steam, 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.

Steam flow meterTo improve high temperature resistance and vibration resistance, our company has recently developed the ZY-LUG improved vortex flow sensor. Due to its unique 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, the maximum flow rate is often much lower than the upper limit of the instrument, and with changes in load, the minimum flow rate is often lower than the lower limit of the instrument. The instrument is not working in its optimal working range. To solve this problem, it is usually necessary to reduce the diameter at the measuring point to increase the flow rate 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 with a length of more than 15D between the variable diameter pipe and the instrument for rectification, which makes 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 vortex flowmeter. 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.

Steam flow meterFor the convenience of use, the battery powered on-site display steam vortex flowmeter adopts low-power 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 temperature compensated integrated vortex flowmeter also comes with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. 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.
