Remote transmission LDG-150 electromagnetic flowmeter

Description :

　　Remote transmission LDG-150 electromagnetic flowmeter

　　The measurement accuracy of this product is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc. Different combinations of PTFE or rubber lining materials and electrode materials such as Hc, Hb, 316L, Ti can adapt to the needs of different media.

　　1、 Characteristics:

　　The measurement of flow rate is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy (0.3-0.5%).

　　There is no obstruction in the measuring pipeline, so there is no additional pressure loss, which has significant energy-saving significance.

　　There are no movable parts inside the measuring pipeline, so the sensor has a long lifespan.

　　The straight pipe section required for the sensor is relatively short, making it easy to install.

　　Reasonable selection of electrode and lining materials can resist corrosion and wear.

　　2、 Structure:

　　a、 Measurement catheter: composed of stainless steel catheter, lining, and connecting flange, it is a carrier for measuring the on-site working conditions of the measured liquid.

　　b、 Measurement electrode: a pair of electrodes installed on the inner wall of the measurement catheter, perpendicular to the axial flow direction, to generate signals for the measured liquid.

　　c、 Excitation coil: The upper and lower excitation coils that generate a magnetic field inside the measuring conduit.

　　d、 Iron core and magnetic yoke: Introduce the magnetic field generated by the excitation coil into the liquid and form a magnetic circuit.

　　e、 Shell: Instrument outer packaging.

　　2. Converter:

　　Is it an intelligent secondary meter that amplifies and processes traffic signals?? After calculation by the microcontroller, it can display flow rate, cumulative measurement, and output signals such as pulses and analog currents for measuring or controlling fluid flow rate.

　　3. Product assembly form:

　　It is divided into two forms: one-piece and split type.

　　a、 Integrated: The sensor and converter are installed together.

　　b、 Split type: Sensors and converters are installed separately, forming a flow metering system through connecting cables.

　　c、 To meet the requirements of measuring different media, there are multiple choices for the lining and electrode materials of sensors.

　　3、 Attention:

　　1. Determination of applicable traffic range. The selection of instrument diameter is determined based on the flow range. For electromagnetic flow meters, they are generally selected in situations where the flow signal is strong and the instrument can work stably for a long time. We suggest that you choose your instrument caliber based on the flow rate flow comparison table (see table below) and refer to the actual operating conditions. We recommend a flow rate range of 1-3m/s, which is beneficial for the instrument to be in a suitable state.

　　2. Selection of lining and electrodes. In addition to determining the diameter and flow range, electromagnetic flowmeters also need to choose relevant conditions such as sensor lining and matching electrodes to improve their economic applicability. The design unit can choose different linings, electrodes, etc. according to the different media of different users

　　3. Pressure and usage situation. In addition to determining the above conditions, the electromagnetic flowmeter should also improve the selection of operating pressure, installation form, shell protection level, explosion-proof requirements, output configuration, and other usage conditions and conditions. The integrated type is suitable for indoor environments with good performance, while the split type is suitable for situations where the sensor is used in harsh environments, with large pipeline vibrations and high temperature of the measured medium. Please choose according to the instrument model markings.
