　　2、 Product features:

　　1. The fully welded or cast structure of the body eliminates the need to consider its sealing, thereby eliminating any interface or gap that could cause blockage and reduce instrument performance due to instrument leakage.

　　2. Convenient applications

　　Intelligent HART communication reduces unnecessary on-site operations

　　3. Wide range of measurement, no need to use multiple instruments in the same process measurement

　　4. Microprocessed electronic components reduce initialization time

　　5. Synchronized analog, digital, and pulse output signals allow multiple devices to monitor and control flow

　　6. The expanded temperature range allows for the measurement of more process media

　　7. Integrated or remote electronic components provide convenient installation

　　8. Reduce the types of spare parts for general parts

　　3、 Installation:

　　Vortex flow meters are sensitive to flow velocity distribution distortion, rotational flow, and flow pulsation in pipelines. Therefore, the installation conditions of pipelines on site should be fully taken into account, and the requirements of the manufacturer's instructions should be followed.

　　Vortex flow meters are sensitive to flow velocity distribution distortion, rotational flow, and flow pulsation in pipelines. Therefore, the installation conditions of pipelines on site should be fully taken into account, and the requirements of the manufacturer's instructions should be followed. Vortex flowmeter can be installed indoors or outdoors. If installed in underground wells, there is a possibility of flooding, and submersible sensors should be selected. Sensors can be installed horizontally, vertically, or obliquely on pipelines, but when measuring liquids and gases, attention should be paid to the installation position to prevent interference from bubbles and droplets.

　　1. Installation of mixed phase fluids

　　Installation requirements for vortex flowmeter

　　(a) Installation of flow meters for measuring gases containing liquids; (b) Installation of measuring gas-liquid flow meter

　　2. Requirements for downstream straight pipe length of vortex flowmeter

　　Installation requirements for vortex flowmeter

　　(a) A 90 ° elbow; (b) Concentric expansion tube; (c) Concentric contraction fully open valve; (d) Two 90 ° elbows on different planes; (e) Half open regulating valve; (f) Two 90 ° elbows on the same plane

　　3. Connection between sensors and pipelines

　　Installation requirements for vortex flowmeter

　　4. Bypass pipeline

　　1) The inner diameter D of the upstream and downstream piping is the same as the inner diameter D 'of the sensor, and the difference satisfies the following condition: 0.95D ≤ D' ≤ 1.1D.

　　2) The piping should be concentric with the sensor, and the coaxiality should not be less than 0.05D '.

　　3) The sealing gasket cannot protrude into the pipeline, and its inner diameter can be 1-2mm larger than the inner diameter of the sensor.

　　4) If cut-off inspection and cleaning of sensors are required, a bypass pipeline should be installed.
