Stainless steel flange vortex flowmeter belongs to a kind of velocity type flowmeter, which is widely used in petroleum, chemical industry, علم المعادن, papermaking and other industries for the measurement of fluids. The flowmeter has no moving parts, strong reliability, دقة عالية, long life, can be in a wide range of flow rate to accurately measure the instantaneous flow of liquid and cumulative flow. It is not affected by medium temperature, ضغط, viscosity and components, and at the same time, it is not blocked, not stuck, not easy to scale, high temperature, high pressure, safety and explosion-proof, suitable for harsh environments. Stainless steel flange vortex flowmeter is divided into two types: integral type and split type, and can output pulse signal or current signal and microcomputer networking.

Stainless steel flange vortex flowmeter performance characteristics:

• 1. Stainless steel flange vortex flowmeter has no movable parts, هيكل بسيط ومتين, long service life and low operating costs.
• 2. The circuit of stainless steel flange vortex flowmeter adopts surface mounting process, compact structure and high reliability.
• 3. Stainless steel flange vortex flowmeter with temperature and pressure compensation can directly measure the mass flow rate, will not be affected by changes in media components or dryness, has a high degree of accuracy.
• 4. New appearance design, the body adopts precision casting process, beautiful appearance, مقاومة درجات الحرارة العالية, corrosion resistance.
• 5. There is a multi-point linear correction function that dramatically improves accuracy. Using high-speed algorithms single pulse by pulse measurement cycle by cycle after the compression or widening calculation only lag a cycle output, to achieve real-time linear compensation.
• 6. Temperature and pressure compensation type built-in or external sensors are automatically corrected for temperature and pressure, and the flow rate of the working condition is directly converted into mass flow rate or volume flow rate under standard condition, which is simpler and more accurate.
• 7. Setting up menus using common operating principles and multiple language interfaces makes it clearer and more convenient.

Stainless steel flange vortex flowmeter installation precautions

• 1. Stainless steel flange vortex flowmeter belongs to the precision instrument, the instrument should be selected to be installed in a dry, ventilated, less dusty place.
• 2. The use of measuring steam instrument, the meter body, piping must be added insulation, the flange should be clamped, there must be no air leakage, otherwise the instrument will be easily damaged.
• 3. Stainless steel flange vortex flowmeter installation is good to choose indoors, away from vibration and strong electromagnetic interference. If outdoors, the meter head can be protected.

Stainless steel flange vortex flowmeter routine maintenance precautions

• 1. Stainless steel flange vortex flowmeter should be regularly cleaned vortex flowmeter probe, testing has encountered a few probe detection holes have been blocked by dirt, or even wrapped up in plastic, directly affecting the normal detection.
• 2. Stainless steel flange vortex flowmeter detects grounding and interception specifics on time to remove external electromagnetic interference. There are times when indication problems are based on electromagnetic interference.
• 3. In order to effectively protect the flowmeter to ensure the accuracy and stability of the detection, it is necessary to do a good job of calibration over a period of time (usually one year).
