LDG-200 Electromagnetic flowmeter features introduction

The measurement principle of the LDG-200 electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. It consists of a sensor and a converter. The sensor is installed on the measuring pipe, and the converter is installed within 30 meters or 100 meters from the sensor. The distance between the two Connected by shielded cable. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. It is mainly used to measure the volume flow rate in conductive liquids and slurries in closed pipelines. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc., widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields for measurement High temperature, high humidity, and inconvenient observation environment. Features of LDG-200 electromagnetic flowmeter are introduced, all digital processing, strong resistance to radiation, reliable measurement, high accuracy, flow measurement range up to 1500:1 ultra-low EMI switching power supply, suitable for a wide range of power supply voltage changes, and good anti-EMI performance. Using a 16-bit embedded microprocessor, it has fast computing speed, high accuracy, and programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and has low power consumption.

Using SMD devices and surface mount (SMT) technology, the circuit has high reliability. There are no moving parts and flow-blocking parts in the pipeline, and there is almost no additional pressure loss during measurement. The range can be modified online on-site according to the actual needs of the user. The measurement results are independent of flow velocity distribution, fluid pressure, temperature, density, viscosity and other physical parameters. High-definition backlit LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand. It has digital communication signal outputs such as RS485, RS232, Hart and Modbus. (Optional) It has self-test and self-judgment functions. The hourly total recording function records the total flow in hours, suitable for time-of-use measurement system (optional). There are three internal totalizers that can respectively display the forward total, reverse total and difference total. , there is a built-in non-power-down always-on function, which can record 16 power-down times.
