product description:
SP-LDE series brine conveying pipe flowmeter, concentrated brine level gaugeAccording to Faraday's law of electromagnetic induction, an induction instrument is used to measure the volume flow rate of conductive medium inside a tube. It adopts embedded technology of single-chip microcomputer to achieve digital excitation, and at the same time, CAN fieldbus is used on the electromagnetic flowmeter, which is the first of its kind in China and the technology has reached the leading level in China.
While meeting the on-site display requirements, it can also output 4-20mA current signals for recording, adjustment, and control purposesIt has been widely used in industrial technology and management departments such as chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage.
In addition to measuring the flow rate of general conductive liquids, it can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids.
Product features:
◆ No flow obstruction 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 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 to store measurement and operation data, ensuring safety and reliability.
◆ It has two types: integrated and separated.
High definition LCD backlit display.
The flow velocity of the tested medium in general industry should be 2-4m/s. In special circumstances, the minimum flow velocity should not be less than 0.2m/s and the maximum should not be greater than 8m/s. If the medium contains solid particles, the commonly used flow rate should be less than 3m/s to prevent excessive friction between the lining and the electrode; For viscous fluids, the flow velocity can be chosen to be greater than 2m/s. A higher flow velocity helps to automatically eliminate the effect of viscous substances attached to the electrode, which is beneficial for improving measurement accuracy.
