Introduction to E+H electromagnetic flowmeters: E+H electromagnetic flowmeters are available in both integrated and split configurations. The output stage features electrical isolation, allowing them to be easily connected to downstream instruments for functions such as flow measurement, control, and regulation. At the same time, the flow meter is equipped with an RS485 communication interface, allowing it to be connected to a computer. Each set of products is calibrated using water flow according to the requirements specified in the order, and it can usually be put into use without any adjustments. Due to its unique advantages, it is now widely used in the measurement of flow rates of various conductive liquids in industrial processes, such as corrosive media like acids, bases, and salts; it is also used for measuring the flow rate of various slurries, thus establishing a distinct field of application. The working principle and components of the E+H electromagnetic flowmeter: The working principle of the E+H electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction. Shanghai Ailin Automation Co., Ltd.: Conductive liquids flow in a magnetic field, cutting through the magnetic field lines and generating an induced electric potential. Expression: E = KBLv, where B is the magnetic flux density; L is the distance between the measuring electrodes; v is the average velocity of the fluid under measurement in the magnetic field; K is a proportionality constant. The E+H electromagnetic flowmeter consists mainly of a flow sensor and a signal converter. The sensor converts the flow rate of the liquid being measured into a corresponding induced electromotive force. The function of a signal converter is to amplify the millivolt-level voltage signal generated by the electromagnetic flow meter, which is proportional to the flow rate, and to convert it into standard direct current, voltage, or pulse signals that can be received by industrial instruments. This allows for the indication, recording, and calculation of flow rates in conjunction with these instruments and controllers. Selection of the installation location for E+h electromagnetic flowmeters: The E+H electromagnetic flowmeter is a highly precise instrument, and strict requirements exist regarding the choice of installation location in order to achieve the desired level of precision. When selecting the installation location, the following requirements should be met: 1. The location where the E+H electromagnetic flowmeter is installed should avoid ferromagnetic objects and devices with strong electromagnetic fields (such as large motors and large transformers), to prevent the magnetic field from affecting the sensor’s magnetic field and flow signal. 2. The installation location of the E+H electromagnetic flowmeter should avoid exposure to sunlight and rain as much as possible, and high temperatures should be prevented. Temperatures above 60°C and relative humidity above 95% can have an adverse effect on the proper operation of the electromagnetic flowmeter, and may even cause damage to the equipment. 3. The installation location of the E+H electromagnetic flowmeter should be chosen in a place that is easy to maintain and access. 4. The E+H electromagnetic flowmeter should be installed at the rear end of the pump; it must not be placed on the suction side. 5. The E+H electromagnetic flowmeter should be installed in a dry and well-ventilated area, and should not be placed in wet locations where water accumulation is likely to occur.
