What are the functions of a vortex flowmeter?
Function
1. The body also integrates temperature and pressure compensation function, which can measure the standard volume flow rate or standard mass flow rate of the fluid..
2、 Fully intelligent and digital circuit design, capable of automatically compensating for measured fluid density or standard condition volume calculation.
3、 The new digital filtering and correction functions make flow measurement more accurate and reliable.
4、 The battery powered type can work continuously for more than two years without the need for an external power source.
5、 The brand new dot matrix Chinese character LCD display is more convenient to use and operate. Additional information: The flow range indicated in the instruction manual for common faults of vortex flow juice refers to the flow range used for specific reference media in the side nucleus, such as liquid, which generally refers to ambient water. When used for other media, the available flow range will vary depending on the viscosity, durability, and density of the media. Due to the use of diesel with a viscosity higher than water and a density lower than water as the calibration medium in the oil flow standard device, the lower limit flow rate of the flowmeter is generally increased accordingly, narrowing the available flow range. Therefore, it is normal for the performance of vortex flowmeters to deteriorate at low flow rates when calibrated on oil flow calibration devices. It is not difficult to infer from this that if liquefied petroleum gas (a low viscosity medium) is used to calibrate the vortex flow juice, the opposite result will be better than water.

There must be sufficient straight pipe sections upstream and downstream. In theory, if there are two 90 ° elbows upstream of the sensor installation point on the same plane, the upstream straight pipe section should be ≥ 25D, and the downstream straight pipe section should be ≥ 5D; if there are two 90 ° elbows upstream of the sensor installation point of the vortex flowmeter on different planes, the upstream straight pipe section should be ≥ 40D, and the downstream straight pipe section should be ≥ 5D; in addition, the regulating valve should be installed outside the downstream 5D of the flow sensor. If it must be installed upstream of the sensor, the upstream straight pipe section of the sensor should be no less than 50D, and the downstream should be no less than 5D. For split vortex flowmeters, the selection of pressure measuring points and temperature measuring points should be based on measurement needs. The pressure measuring point should be at 3-5D downstream of the sensor, and the temperature measuring point should be at 3-5D downstream of the sensor. Downstream 6-8D. We generally recommend customers to use an integrated vortex flowmeter with temperature voltage code compensation function. This intelligent flowmeter integrates temperature sensors, pressure sensors, and flow sensors, which can improve the measurement accuracy of the flowmeter itself and synchronously display the temperature and pressure values of the medium in the pipeline on the LCD head of the instrument itself. More importantly, it avoids the construction trouble of setting up additional temperature and pressure measurement points.
