1210501235, also known as electromagnetic flowmeter, is one of the most commonly used instruments in the industry. It belongs to the miscellaneous category of instrumentation, and is used for measuring the volumetric flow rate of an electrically conductive liquid or gas. This paper explains the application field and working principle of 1210501235 in detail.

Application field

1210501235 is mainly used to measure the flow rate of conductive liquids, such as sewage, river water, sea water, paper pulp, paint, etc. It is also used in some process control applications, such as controlling the liquid level in tanks or reactors, as well as controlling the composition of solutions. Additionally, 1210501235 can be used to measure the flow rate of some pure liquids, such as potable water and oil, and even some non-conductive liquids, such as petroleum, acid, alkaline, and other fluids.

Working principle

The working principle of 1210501235 is based on the Faraday\'s law of electromagnetic induction. When a conductive liquid passes through the magnetic field generated between the exciter coil and the detector coil, an electromagnetic induction force is generated, which causes a signal voltage output on the detector coil. The magnitude of this signal voltage is proportional to the velocity of the liquid. The signal voltage is then amplified and converted into a digital signal, which is sent to the display unit for displaying the flow rate.

To ensure that the signal voltage is proportional to the velocity of the fluid, the measuring tubes of 1210501235 are designed in accordance with the laminar flow condition. This helps to reduce the interference caused by turbulence and swirl in the tube. The instrument also takes into account the pressure and temperature of the fluid, as well as the shape and size of the tube, and adjusts the output voltage accordingly.

1210501235 also consists of a bypass valve, which helps to adjust the flow rate of the fluid in order to keep it within the flow range of the instrument. Moreover, 1210501235 is equipped with an analog interface for connecting to a process control system, allowing for online monitoring and control of process variables.

In conclusion, 1210501235 is a versatile instrument, capable of measuring the flow rate of various liquids and gases. It is widely used in industry and has many applications, such as controlling the liquid level in tanks or reactors, as well as controlling the composition of solutions. The working principle of 1210501235 is based on the Faraday\'s law of electromagnetic induction, and the instrument takes into account factors such as pressure, temperature, and the shape and size of the tube for accurate readings.
