Electromagnetic Flux Meter


Usually, the instruction sheet supplied with the flow meters specifies the working pressure and temperature for the liquid media used. Then there will be an understanding and revision of your application requirements. This includes the liquid used, the temperature of the liquid, the flow range and the operating pressure. One of the by-products of mining activities is the production of thick, heavy mud that is pumped while minerals are removed.

Two field coils are placed in the magnetic flux meter using bars and generate a magnetic field through the tube to measure. The electrodes, installed on the sides of the tube or tube at a right angle, absorb the electrical voltage. For protection and to prevent short circuit, a coating is placed in the wall sensor between the conductive liquid and the metal body. Magnetic flux meters for abrasive service generally have a measure of low speed (usually below 5 – 6 feet / sec) to reduce wear. In the abrasive suspension service, the flow meter must operate above the rate at which the solids settle despite increased wear. These problems can change the range of the flow meter, so the size may differ in size for an equivalent flow of clean water.

MagFlux for fully functioning pipes has no moving parts, which offers the advantage that the flow meter does not affect the pressure conditions of the piping system. The modern modular design is flexible and can be used to measure many types of flow in conductive liquids. Due to the đồng hồ nước điện tử high reliability of the data, the flow meter is widely used to eliminate water waste from leakage and as a measure of waste water flow. One of the concerns regarding the installation of a magnetic flux meter may be the initial cost, as specially designed meters can be expensive.

Failure to meet the manufacturer’s installation requirements often leads to poor precision or inconsistent performance. As the name implies, volumetric flow meters measure flow by calculating the volume of a liquid. Flow is often guided by a burglary measuring device, such as a turbine or hole plate, which then measures the speed of the liquid in proportion to the volume of the passing material. Volumetric flow meters are the most meterty types today and include turbine, magnetic, positive displacement, ultrasonic and vortex meters, just to name a few. To choose the perfect flow meter for your needs, focus on the details of your individual application rather than the specifications of the flow meter production. Due to their profitability, longevity and high precision, electromagnetic flux meters are often the first choice for many people.

Faraday’s law establishes that the voltage generated is proportional to the movement of the flowing liquid. The electronic transmitter processes the voltage signal to determine the liquid flow. Pallet wheel gauges include those with rotating paddle, propeller wheels and oscillating discs (multiple beam types). The rotating component is designed to give a pulse when passing a magnetic or optical sensor.

Whether you are using a full meter mag-meter or a full profile mag insertion meter, make sure that the meter you have chosen accurately provides the necessary precision. Since PD meters only measure current when fluid passes through, they are ideal for applications where measurement is critical to calculating fluid usage. For example, TCS 700 series rotary pallet meters are widely used in the oil and gas supply industry, while aperture parameters are usually installed on residential or municipal water and gas pipes. The liquid-driven design also makes flow meters with positive displacement one of the most cost-effective options because they don’t need an external power supply to work.

Ultrasonic flow meters are non-invasive volume flow meters based on transit technology or Doppler effect. A flow meter during transit time measures the frequency change between upstream and downstream ultrasonic pulses projected into and through the tube. A Doppler flow meter measures the frequency change when an ultrasonic signal is reflected in particulate matter or moving gas bubbles. Electromagnetic flux meters or induction flux meters work with conductive liquids by measuring the flux through a controlled magnetic field. Magnetic flux meters use the principle of Faraday’s Law of Electromagnetic Induction to measure the flow of liquid in a tube. In the tube parts of the magnetic flux meter, a magnetic generated field is generated and channeled into the liquid that flows through the tube.
