Jing Chuan JC-LDG / S EPA sewage water meter meter meter ammonia hydrogen peroxide meter seawater flow meter
Flow measurement accuracy River JC-LDG / S EPA sewage flow meter sea water meter meter meter hydrogen peroxide is widely used in petroleum, chemical, metallurgy and other fields, for conductivity is greater than 5 us / cm conductive liquid. Measuring tube no activity and blocking parts, no pressure loss measurements affect the density, viscosity, temperature, pressure and electrical conductivity changes from the media liner material and electrode material selection, has good corrosion resistance and abrasion resistance low-frequency square wave excitation, from frequency and various spurious interference field can be widely used in environmental protection, chemical, paper, textile, metallurgy, food, brewing and other industrial sectors as well as to field drainage works, water conservancy construction, especially in the sewage treatment works applied more widely.

Flow measurement from the fluid density, affect the viscosity, temperature, pressure and electrical conductivity changes, the sensor sensing the voltage signal and a linear relationship between average velocity and therefore high accuracy.
Unimpeded flow measurement tube parts, so there is no additional pressure loss; measurement tube no moving parts, so very long sensor life.
Since the induction signal should be successful in the whole space formed in the magnetic field, it is the average cross section of the pipe, so the sensor straight pipe required for a shorter length of 5 times the pipe diameter sensor part only lining and electrodes the measured liquid contact, as long as a reasonable choice of electrode and lining material can be resistant to corrosion and wear resistance.
LDE The converter uses the latest international most advanced microcontroller (MCU) and surface mount technology (SMT), reliable performance, high accuracy, low power consumption, zero stability, convenient parameter setting. Dot matrix Chinese display LCD, display the cumulative flow , instantaneous flow velocity, flow percentage and so on. Bi-directional measurement system can measure forward flow, reverse flow.
