AK-DWM Digital Water meter

Illustrate

AK-DWM Digital Water meter can be used to measure liquid

Summary
The digit water meter  is suitable for single-direction water flow, can not used in corrosive liquid.  The property is stable and reliable, high accuracy, long working life.

Characteristics

1. Digital display, easy to read, display total flow and current flow, measure the total flow in a certain time.
2. Display high resolution total flow in test mode, the minimum resolution of small size is 0.00001m3.
3. With Modbus and RS485 communication module, can achieve long-distance meter reading. It is low-consumption, built-in Li battery, and can match a remote display.
4. With reset function, when enter into test mode, the total flow can reset, it is more suitable for industry dosing.

Signaling principle

The impeller rotation causes the flip of a magnetic field, magnetic field turn every week, wiggins send out a set of positive and negative pulse. Pulse frequency related to impeller rotational speed (magnetic filp frequency), each positive and negative pulse width approximately 20-30uS, pulse height not less than 1. 5 V.
Operating voltage: 3 ~ 6 V
Working current: static one is less than 1ua; maximum speed is less than 3ua;
Output: rectangular wave. (high level is equal to the supply voltage);
Wiring: nether positive nor negative electrode
