3. Introduction to LUGB type vortex flowmeter

LUGB type vortex flowmeter is a precision instrument family manufactured based on the Karman vortex principle for measuring the flow of liquid, gas, and steam in sealed pipelines. Due to the sealed detection element inside the detection body, it does not come into contact with the measured medium, and there are no movable parts inside, it does not require on-site maintenance. Therefore, it is highly praised by users and widely used for measurement management and process control in the petroleum, chemical, metallurgical pharmaceutical, thermoelectric, and papermaking industries.

4. Vortex flowmeter Analysis of Several Fault Causes

The common causes of malfunctions in vortex flowmeters mainly include selection problems, parameter tuning errors, secondary instrument failures, connection problems, installation problems, line failures, environmental factors, and debugging problems. The specific analysis is as follows: Improper selection of caliber: After design selection, due to changes in process conditions (such as partial equipment shutdown), the actual flow rate is lower than the original design flow rate, resulting in inaccurate or no indication at small flow rates. For example, the pipeline originally designed for use by multiple devices had a reduced actual flow rate due to the discontinuation of some equipment, and the original selected diameter was too large, resulting in an increase in the lower limit of measurable flow rate. Accuracy cannot be guaranteed at low flow rates. Improvement measures: Combining parameter tuning to improve indication accuracy;
