LDE-500 electromagnetic flowmeter

Description :

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid.

　　1、 Characteristics:

　　The sensor adopts an integral welded structure with good sealing performance;

　　The structure is simple and reliable, with no moving parts inside and almost no pressure loss;

　　The measurement accuracy is not affected by changes in physical parameters such as pressure, temperature, density, viscosity, etc. of the measured medium; Accuracy is not sensitive to changes in velocity distribution (except for vortices);

　　Equipped with conductivity measurement function, it can distinguish whether the sensor is empty or not; Adopting a 16 bit embedded microprocessor, it has fast computing speed and high accuracy; There are two integrators inside, which display forward and reverse accumulation and difference accumulation respectively; Capable of outputting RS485 or RS232C digital communication signals.

　　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: Three types of excitation frequencies are standard, 1/10, 1/16, and 1/25 power frequency (1/4, 1/8, and 1/32 are optional), to meet more measurement needs;

　　Operation method: It has two functions: key operation and magnetic key operation. The operation is simple and fast, easy to learn and understand. Infrared handheld keyboard for remote non-contact operation.

　　3、 Attention:

　　1. The ambient temperature or the radiation temperature on the surface of the flowmeter converter is greater than 60 ℃.

　　2. In situations where pipeline vibration is significant.

　　3. In situations where the aluminum casing of the converter is severely corroded by corrosive gases.

　　4. In places with high humidity or corrosive gases on site.

　　4、 Environmental conditions:

　　Flow meters, especially those with intelligent LCD display screens, should be installed in a location that avoids direct sunlight as much as possible, and the ambient temperature should be between 5C and 55C.

　　Avoid strong interference sources

　　Choose a location without strong electromagnetic field radiation to install flow meters, avoiding equipment that can easily cause electromagnetic interference such as motors, transformers, and frequency converters. The measurement principle of a flowmeter is based on Faraday's law of electromagnetic induction, and the raw signal it generates is very weak, less than millivolts. If there is strong electromagnetic field radiation near the flowmeter, it will affect the accuracy of the measurement and may even malfunction.
