Description :

　　This product has measurement value power-off protection and air traffic control alarm function. The flow direction of the fluid can be set, so the installation of the sensor is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.

　　1、 Technical parameters:

　　1. Provide display interfaces in both Chinese and English;

　　2. It can directly display the instantaneous flow rate, cumulative flow rate, percentage flow rate, and flow velocity in both forward and reverse directions according to the engineering unit;

　　3. There are 6 types of flow units to choose from (L/m, L/h, m3/m, m3/h, GPM, GPH);

　　4. 4~20mADC load 0~750, scale flow rate (upper limit of range) can be set arbitrarily;

　　5. By setting the pulse coefficient, each pulse can represent a certain volume flow rate, or output a 0-2kHz frequency signal proportional to the flow rate;

　　6. Provide traffic upper and lower limit reporting function;

　　7. RS485 interface, bidirectional communication. The working parameters of the flowmeter can be set and modified through the upper computer;

　　8. When the fluid is stationary, the zero point of the flowmeter can be automatically calibrated through the buttons on the panel;

　　9. Damping adjustment can be set within a range of 1 to 99 seconds;

　　10. Power supply voltage: 220VAC/24VDC type;

　　11. Environmental temperature: -20~60 ℃;

　　12. Protection level: IP65;

　　13. Explosion proof grade: ExdibIIBT4.

　　2、 Technical features:

　　1. Suitable for liquid flow detection with conductivity greater than 5 μ s/cm. Changes in conductivity do not affect performance changes

　　2. Electromagnetic flow meters have long-term high measurement accuracy and are actually not affected by fluid physical properties

　　3. Easy to put into operation, the flowmeter is automatically set within the range of 0-10m/s, without the need to change the measurement range

　　4. All components in contact with the tested medium have good corrosion resistance and wear resistance, with a wide range of applications

　　5. There are no movable parts or flow blocking components in the pipeline, and there is almost no additional pressure loss during measurement

　　6. The measurement results are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc

　　3、 Length of straight pipe section:

　　Attention should be paid to avoiding components that generate eddy currents, such as valves, elbows, and bypasses. The straight pipe sections upstream and downstream of the flowmeter should be extended as much as possible, and if necessary, rectifier pipes should be installed to ensure that the upstream straight pipe section of the flowmeter must be at least 5 DN (measuring pipe diameter) and the downstream must be at least 2 DN.

　　Liquid conductivity must be uniform and stable

　　Do not install the flowmeter in areas where the conductivity of the fluid being measured is extremely uneven. If different media are injected upstream, it will result in uneven conductivity and affect the measurement. In this case, it is recommended to move the injection port downstream; If it is necessary to inject from upstream, it should be kept as far away from the flow meter as possible. It is generally recommended to maintain a distance of at least 20 DN to ensure thorough and uniform mixing of the liquid.
