1. Common faults and troubleshooting methods of vortex flowmeter?

Vortex flowmeter is a flow measurement instrument without moving parts, which reflects the flow velocity by measuring the vortex frequency downstream of obstacles in the flow path, thus achieving the purpose of measuring flow. This flowmeter has the advantages of wide application range, high measurement accuracy, low wear, linear output signal and long-distance transmission, easy installation and maintenance. When the flowmeter displays abnormally, it is necessary to check whether the process condition meets the instrument requirements and whether the process flow falls within the range that the flowmeter can measure. If this requirement is not met, the flowmeter display will be abnormal. 2. The medium that the flowmeter can detect should be single-phase fluid. If there is a gas-liquid two-phase phenomenon in the medium, the flowmeter display will be abnormal. When there is a malfunction in the flowmeter, it is necessary to correctly distinguish whether the instrument is displaying or if other secondary instruments are malfunctioning. If the flowmeter has an output leakage but the display instrument does not display, this beam type fault should be on the display instrument. 4. Confirm that the fault is caused by the flow meter, and troubleshoot it according to the following table.

2. Characteristics of Vortex Flow Meter

1. The structure is simple and sturdy, with no movable parts, high reliability, and very reliable for long-term operation.

Secondly, installation is simple and maintenance is very convenient. Thirdly, the detection sensor does not directly contact the measured medium, with stable performance and

long lifespan. 4. The output is a pulse signal proportional to the flow rate, with no zero drift and high accuracy. 5. Wide measurement range, with a range ratio of up to 1:10. 6、 Less pressure loss, lower operating costs, and more energy-saving significance. Within a certain Reynolds number range, the output signal frequency is not affected by the physical properties and composition changes of the fluid. The instrument coefficient is only related to the shape and size of the vortex generator, and there is no need to compensate when measuring the fluid volume flow rate. After replacing the accessories, there is generally no need to recalibrate the instrument coefficient. Widely applicable, the flow rates of steam, gas, and liquid can be measured. The verification period is two years. The inner diameter range of the LUGB type vortex flow sensor is 25-300mm (full tube type), and the inner diameter range of the KTLUI type insertion vortex flow sensor is 350-1200mm (insertion type). The full tube type measures liquid with an accuracy of 1%, steam and gas with an accuracy of 1.5%, the insertion type measures liquid with an accuracy of 2%, and steam and gas with an accuracy of 2.5%. The measured medium temperature is -20~150 ℃, -40~250 ℃,+100~350 ℃ (tube type only), and the output signal is a broken three wire voltage pulse. The three wire system is 4-20mA, and the two wire system is 4-20mA.
