AquaShield WiFi Smart Water Level Sensor

The product is suitable for various water level control occasions, such as HVAC system, hot water process, municipal drainage, boiler, water tower, storage tank, breeding irrigation etc.

Main Features:

1. Real-Time Supervision: APP can display the current water level,

2. Turn on/off equipment (relay 1) remotely via App. Users can also control it on/off by manual switch button B.

3. Two relay outputs: Relay 1 control water level, Relay 2 for Anti water dry heating protection.

4. Preset"Add water" or "Pump water" working mode, can auto turn on/off relay 1 when it reaches to the preset water level value.

5. Set upper and Lower limit value of water level alarm via APP, real-time push alarm notification to users' smartphone.

6. Can set relay 1 running or delay working time.

A: WIFI configuration button

B: On/Off Switch of Relay Output 1: Users can press the button B to switch on/off Relay 1 manually.

The manual switch B is only effective when the current water level is between the preset start and stop- water level value.

C: WIFI Configuration Indicator/ Relay Output 1 Status Indicator

D: Relay Output 2 Status Indicator

Remark:

Terminal 1: No use.

Terminal 2: 100% water level

Terminal 3: 75% water level

Terminal 4: 50% water level

Terminal 5: 25% water level

Terminal 6: Public water point (COM)

Terminal 7,8: Relay Output 1 (Normal Open)

Terminal 9,10: Relay Output 2 (Normal Open)

Terminal 11,12: AC220V Power Supply (available from AC210V to AC240V ).

Wiring Connection (Take" add water" as example)

Water level rising: water level < 25% electrode; App display 0%; reach to 25%, App display 25%; reach to 50% , App display 50%; reach to 100%, App display 100%.

Water level reducing: Water level below 100%, App display 75%; below 75%, App show 50%; below 50%, App display 25%, below 25%, App display 0%.

Normally Relay output 1(terminal 7.8) connects with water pumps, used for controlling water pump on/off.

Relay output 2 ( terminal 9.10 ) is used for Anti water dry heating protection.

In add water mode, normally relay output 2（terminal 9,10）can connect with heater, used for auto controlling heater on/off.

1. Device Name: Can be modified

2. On/Off Switch of Relay 1: It is only effective when the current water level is between the preset start and stop- water level value.

3. Display real time water level.

Five water levels: 0%, 25%, 50%, 75%, 100%

4. Choose working mode: Adding water or Pumping water.

5. Set water level value of auto starting/stopping.

For example: if you want equipment auto-starts to pump water when the water level reaches to 100%, but auto- stop it when the level lower than 25%. You can set pumping mode, level on 100%, level off 25%.

6. Anti Water Dry heating protection: In adding water mode, auto turn on/off heater. When water level is lower than 25%, auto-turn off relay output 2, when water level is ≥25%, auto-delay 15s to turn on relay 2.

7. Enable/disable of alarm notification.

8,9. Set upper and Lower limit value of water level alarm.

10. Set delay time of relay 1 starting.

11. Show current sensor status.

12. Set limited running time of relay output 1.

Control Mode 1: Add water

Water level ≥ preset" stop level", relay output 1 disconnect, stop to add water; Water level < start up level, relay output 1 connects, start to add water.

Anti Water Dry heating protection: water level < 25%, relay ouput 2 disconnect, stop heating; Water level ≥25%, relay output 2 delays 15 seconds connect, start heating.

Control Mode 2： Pump water

Water level < preset " stop level", relay output 1 disconnects, stop to pump water; Water level ≥ start up level, relay ouput 1 connects, start to pump water.

In pumping water mode, relay 2 is an alarm output. Water level ≤ preset lower limit alarm value or Water level≥ upper limit alarm value, relay ouput 2 connects.

Time-limited control

Mode 3: Time-limited adding water

Water level < start up level, relay output 1 connects, starts to add water, at same time, starts the timer. Relay 1 will auto disconnect when it reaches to the preset limited time of running, stop adding water.

Mode 4: Time-limited pumping

Water level ≥ start up level, relay ouput 1 connects, start to pump water, at same time, starts the timer. Relay 1 will auto disconnect when it reaches to the preset limited time of running, stop pumping water.

Upper and lower limit Alarm Notification

For example : Preset alarm lower limit of water level is 25%, alarm upper limit is 75% . When water level is lower than 25% or higher than 75% , it will push alarm notification to users' smartphone via APP.
