Working principle and applicable range of imported orifice plate flowmeter?

The imported orifice plate flowmeter is a high rangeability differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, pressure transmitter). It can measure the flow rate of gas, steam, liquid and water, and is widely used in process control and measurement in the fields of petroleum, chemical industry, metallurgy, power, heating, and water supply.

Common problems and solutions for target flow switches

While inexpensive, target flow switches suffer from design flaws that make them susceptible to external factors. This results in a shorter lifespan and higher maintenance costs, a major drawback of this type of switch. For your reference, we have compiled some common problems and solutions for target flow switches:

Working principle and internal structure of paddle flow switch?

A target flow switch is a sensor controller that measures the flow rate of the medium in the pipeline and transmits the on/off signal to the backend device in real time. The flow switch is mainly installed online or inserted in pipelines of water, gas, oil and other media. When the flow rate is higher or lower than a certain value, it triggers the switch to output an alarm signal. After receiving the signal, the system can make the corresponding actuator operate.

How should an earth pressure sensor be wired when measuring pipeline pressure?

Soil pressure measurement is an important task in the theoretical research of soil mechanics and engineering testing. Using soil pressure sensors, the contact stress between the surface of structures such as subgrades, retaining walls, dams, and roads and the soil medium, as well as the original stress state of the soil layer, can be obtained. This is used to evaluate the working state of the construction site and verify the theory of soil stress distribution. Soil pressure sensors are often used to measure the stress in soil such as airport runways, railway embankments, highway subgrades, and earth-rock dams. They are also used to measure the soil pressure exerted on underground oil, gas, and water pipelines, protective engineering, subways, tunnels, and other underground structures. How should the soil pressure sensor used to measure pipeline pressure be wired?

What are the common types of oil flow meters?

An oil flow meter is a tool for measuring the volume or mass of oil, and can realize the mutual conversion between volume and mass. It can be widely used in flow measurement in petroleum, chemical industry, medicine and health departments. The types of oil flow meters that meet the requirements of high pressure and high rangeability measurement in gas storage are: average velocity tube flow meter, target flow meter, channel flow meter, insertion ultrasonic flow meter, and clamp-on ultrasonic flow meter. Below, several types of oil flow meters and their structures and characteristics are introduced.

Could the water flow meter manufacturer introduce the characteristics of the water flow meter?

The flow meter manufacturer says that the flow meter consists of two parts: a sensor and a converter. It works based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 S/C. It is an inductive instrument for measuring the volumetric flow rate of conductive media. It can be used to measure the volumetric flow rate of general conductive liquids, strong corrosive liquids such as strong acids and strong alkalis, slurries, pulp, and uniform liquid-solid two-phase suspensions. It is widely used in flow measurement in various industrial sectors such as petroleum, chemical, metallurgical, textile, papermaking, environmental protection, and food industries, as well as in municipal management, water conservancy construction, and river cooling.

Basic introduction to target flow switches?

In the structure of the target flow switch, the force required for blade recovery uses magnetic force instead of a general spring sheet, making the flow switch more stable and durable, and less sensitive to pressure peaks. This target flow switch has the advantages of instantaneous response, low pressure drop, high pressure resistance, and more repeated switching. Opening and closing depend only on the flow rate and are independent of temperature or pressure.

What should I do if the electromagnetic flow meter signal is too weak?

Electromagnetic flow meters are commonly used pipeline measuring instruments. They are unaffected by the temperature, viscosity, and density of the fluid, and also have good wear and corrosion resistance. Therefore, they are widely used. Some users sometimes encounter the problem of weak signals from electromagnetic flow meters. So what should you do if the signal from the electromagnetic flow meter is too weak? Below, eletta will give you a detailed introduction.
