Select vortex flowmeter should pay attention to what? Here we give you two tips on this topic;
Wide range of applicable media, low prices, in the industrial production of gas flow metering play a role.
Quality is related to two parts: 1. Probe 2. Circuit board 1. Probe: There are two piezoelectric crystals inside, one for anti-vibration interference and one for testing. The probe lead is the two leads of the test piece. The probe housing is inserted into the vortex body tube wall and fixed to the vortex body tube wall by a fixed flange. The probe works well below 300°C and can withstand up to 350°C. If the temperature is higher, the sealed porcelain body will be damaged, which will degrade the probe performance and even damage the probe. We can use the multimeter “×10k†file to check the two leads of the probe. It should be infinite. If there is a resistance, the performance of the probe will decline. If it is below several tens of kiloohms, the probe will be damaged.
Second, the circuit board: its design is directly related to the vortex street signal is correct or not, we can usually oscilloscope to view the flowmeter produced by the wave when working.
In the production process, the seal between the sensor and the body is very important. If the seal is not good, the body will leak. Before the delivery, the pressure test is performed and the flow calibration is performed by the calibration device.
