LDG-500 electromagnetic flowmeter

Description :

　　This product can set the direction of fluid flow, so the sensor installation is not limited by the direction of liquid flow, and can achieve bidirectional flow measurement.

　　1、 Characteristics:

　　The structure is simple, reliable, without moving parts, and has a long working life.

　　No flow blocking components, no pressure loss or fluid blockage.

　　No mechanical inertia, fast response, good stability, can be applied to automatic detection, adjustment, and program control systems.

　　The measurement accuracy 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.

　　There are various flow meter models available, including pipeline type and plug-in type.

　　Using EEPROM memory, the storage of measurement and operation data ensures safety and reliability.

　　It has two forms: integrated and separated.

　　High definition LCD backlit display.

　　2、 Main technical data:

　　Power supply: 85V-250VAC/16V-36VDC;

　　Instrument display: High definition backlit LCD display (126 x 48 dot matrix), which can simultaneously display instantaneous, cumulative flow and other information and related units, with Chinese/English menu support;

　　Communication interface: It has digital communication signal outputs such as RS485, RS232, Hart, and Modbus;

　　Anti interference: Built in comprehensive anti-interference multi-level protection circuit with full digital processing, significant anti-interference performance, effectively eliminating on-site vibration and power frequency interference;

　　Data storage: With comprehensive data backup and recovery functions, on-site maintenance free;

　　Excitation method: There are three standard excitation frequencies, 1/10, 1/16, and 1/25 power frequency (1/4, 1/8, and 1/32 are optional), to meet more measurement needs.

　　3、 Installation:

　　1. Horizontal and vertical installation

　　Sensors can be installed horizontally and vertically, but it should be ensured to avoid the influence of sediment and bubbles on the measuring electrode, and the electrode axis should be kept horizontal. When installed vertically, the fluid should flow from bottom to top. The sensor cannot be installed at the highest position of the pipeline, as this position is prone to the accumulation of air bubbles.

　　2. Ensure full pipe installation

　　Ensure that the flow sensor is filled with the measured fluid in the pipeline during measurement and that there is no non full pipe state. If the pipeline is not full or the outlet is empty, the sensor should be installed on a siphon tube.

　　3. Installation between bends, valves, and pumps

　　To ensure the stability of the measurement, a straight pipe section should be installed before and after the sensor, with its length given. If it cannot be achieved, a current stabilizer should be used or the cross-sectional area of the measurement point should be reduced.
