LDG-32 electromagnetic flowmeter

Description :

　　This product is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, salts, etc.

　　1、 Technical parameters:

　　Nominal diameter (mm): Pipeline PTFE lining: DN10~DN600 Pipeline rubber lining: DN40~DN1200

　　Flow direction: positive, negative, net flow

　　Range ratio: 150:1

　　Repetitive error: ± 0.1% of the measured value

　　Accuracy level: Pipeline type: 0.5 level, 1.0 level

　　Temperature of the tested medium: ordinary rubber lining: -20 to+60 ℃

　　High temperature rubber lining: -20 to+90 ℃

　　PTFE lining: -30 to+100 ℃

　　High temperature PTFE lining: -20 to+180 ℃

　　Rated working pressure: (high pressure can be customized) DN6-DN80: ≤ 1.6MPa DN100-DN250: ≤ 1.0MPa

　　DN300－DN1200：≤0.6MPa

　　Conductivity range: The conductivity of the measured fluid is ≥ 5 μ s/cm

　　2、 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.

　　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. Sensors cannot be installed at high positions in pipelines, as this location 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 measurement stability, straight pipe sections should be installed in front and behind the sensor. If it cannot be achieved, a current stabilizer should be used or the cross-sectional area of the measurement point should be reduced.

　　4. Sensors cannot be installed at the inlet of the pump

　　To avoid negative pressure, the sensor should not be installed at the inlet of the pump, but at the outlet of the pump.
