What are the components of an intelligent vortex flowmeter?

The intelligent vortex flowmeter is composed of two main parts: the meter head and the housing.. Signal output method in the header: output signal (signal interface is M20 × 1.5 internal thread) pulse voltage output signal: high level 8-10V, low voltage 0.7-1.3V, (explosion-proof type: high level 4-5V, low level 0.7-1.3V) pulse duty cycle of about 50%, transmission distance of 100 meters standard current output signal: DC4-20mA, allowing external load resistance less than 600Q (power supply DC24V), transmission distance of 3000 meters Vortex flowmeter is mainly used for flow measurement of industrial pipeline fluid media, such as gas, liquid, steam and other media. Its characteristics are small pressure loss, wide range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. Without any movable mechanical parts, it has high reliability and requires minimal maintenance. The instrument constant can be stable for a long time. Plug in instruments are installed at the insertion port in pipelines, while ball valves can be continuously loaded and unloaded.

2. Intelligent Vortex Flow Meter Diameter and Flow Range

Instrument diameter and flow range are key parameters for selecting intelligent vortex flow meters.

. Flow meters with different diameters have different measurement ranges and output frequency ranges. For example, for a 150mm caliber flowmeter, the measurement range for liquid gas and steam is from 3m/h to 636m/h, and the output frequency range is between 4Hz and 446Hz; For larger 250mm apertures, the measur Intelligent vortex flowmeter

ement range is extended to 65-1250m/h, and the output frequency range is 1.5-25Hz. The selection of these parameters needs to be determined according to actual application requirements. The application of intelligent vortex flowmeter in biogas pipelines requires special attention, as the flow rate of biogas pipelines is relatively small and usually requires reducing the diameter to ensure measurement accuracy. It is very important to choose a suitable Jiaoling flowmeter in biogas measurement. Firstly, it is necessary to understand the minimum flow rate, common flow rate, and maximum flow rate of biogas to ensure that the flow meter can effectively cover the measurement requirements. Meanwhile, as the biogas measurement site may not have a power source, a battery powered vortex flowmeter can be chosen to meet the on-site power supply conditions. If it is necessary to bring the display of the flowmeter indoors, an integrated vortex flowmeter can be selected, and the output signal can be transmitted to the indoor flow integrator through a cable to achieve on-site display. When installing a vortex flowmeter, special attention should be paid to the following points:

1. Avoid frequent opening and closing of valves near the upstream of the installation point to protect the service life of the sensor.

2. Try to avoid installing on very long overhead pipelines to prevent the sensor from sagging and causing seal leakage. If it must be installed on a long pipeline, a pipeline fastening device should be installed 2D upstream and downstream of the sensor. 3. Ensure that the fluid flow pattern at the inlet is not disturbed. The length of the upstream straight pipe section should be approximately 15 times the diameter of th
