Strong acid flowmeterWidely used in production process flow measurement and control in industries such as petrochemicals, steel metallurgy, water supply and drainage, water conservancy irrigation, water treatment, total control of environmental wastewater, papermaking, medicine, food, and other agricultural sectors; Suitable for measuring the total amount of conductive liquids.
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.

The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements; In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level can be chosen, such as 1.5, 2.5, or even 4.0,.
2. When measuring medium flow rate, instrument range, and caliber, the full flow rate of the flowmeter can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.
3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.
4. There should be ample space around for easy inspection and maintenance.

It is a volumetric flow measurement instrument that is not affected by the temperature, viscosity, density, and conductivity (within a certain range) of the measured medium during the measurement process.
The range is wide, up to 1:100. In addition,Strong acid flowmeterIt is only proportional to the average flow velocity of the measured medium, and is independent of the axisymmetric flow state (laminar or turbulent).
Strong acid flowmeterNo mechanical inertia, sensitive response, can measure instantaneous pulsating flow rate, and has good linearity. Therefore, the measurement signal can be directly converted linearly into a standard signal output using a converter. LD-T type can indicate on-site, while LD type can transmit over long distances.

Introduction:
It is developed based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive fluids. Due to its unique characteristics, it has been widely used in the measurement of various conductive liquids in industry. Mainly used in industries such as chemical, papermaking, food, textile, metallurgy, environmental protection, and water supply and drainage, it can achieve system control when paired with computers.
There are no movable parts or flow barriers, which will not cause pressure loss, wear, blockage, or other issues.
