Corrosion resistant spiral vortex flowmeter

Corrosion resistant spiral vortex flowmeterparameter

1. Working power supply

Internal power supply: 3V lithium battery, power consumption ≤ 0.3mW, can be used for two years;

External power supply: 24VDC ± 15%, power consumption ≤ 1W.

2. Output signal

Pulse signal: Three wire pulse signal output, transmission distance ≤ 200m;

(4~20) mA standard analog signal: Linear for analog signals in the flow range of (0~Qmax) m3/h, transmission distance ≤ 1500m, connection method is two-wire or three wire system.

RS485 communication interface signal, directly connected to the upper computer for remote transmission of instrument related parameters and real-time data. At the same time, it can carry 8 flow meters with a dedicated MODEM.

3. Explosion proof grade: Ex D Ⅱ BT4

feature

1. The circuit adopts surface mount technology, compact structure, and high reliability

2. Adopting low-power high-tech, it can work with both internal and external power sources, and has low overall power consumption;

3. The software has powerful functions and excellent performance;

4. No mechanical movable parts, good stability, not easily corroded, no need for mechanical maintenance;

5. The requirements for the front and rear straight pipe sections are low, with a front length of ≥ 3DN and a rear length of ≥ 1DN;

6. Adopting a high contrast LCD display, it can display cumulative flow and instantaneous flow, with convenient and clear readings;

7. The instrument has a password setting function to prevent unauthorized settings;

8. The instrument has the function of saving power outage data;

9. Xindi displays the flow value and comes with pulse signals and (4~20) mA standard analog signals for remote transmission output, making it easy to connect with secondary instruments.
