TankMate TMR3 Tank Level Sensor

Product Information

The TankMate TMR3W Tank Level Sensor is a device designed to accurately measure the level of water in a tank. It comes with various components including the TMR3 Tank Level Sensor, O-ring, Lens, Blue rubber gasket, fixing screws, Masonry wall plugs, and a Magnet.

Product Usage Instructions

1. Step 1: Install the Gasket and Lens
   • Insert the wall plugs (required for concrete tanks only).
   • Put the blue rubber gasket back into place – check that it is aligned with the center hole and fixing holes.
   • Insert the white plastic lens, with the rubber O-ring facing up.
   • Important: Press the READ button underneath the sensor before fixing it down onto the tank. Check the LED status:
   • Blinking green, then solid BLUE: connected to the network.
   • Blinking ORANGE: ready to be positioned (10 sec.).
2. Step 2: Secure the TankMate Sensor
   • While the status light is blinking ORANGE, place the sensor onto the tank, on top of the gasket.
   • Wait 20 seconds, then refresh the TankMate app (swipe down).
   • Check that an initial level reading was recorded (reading date / time in app).
   • Secure the sensor with 4 x stainless screws provided – do not overtighten.
3. Additional Information: Quick Start Guide
4. Step 3: Account / App Setup
   • Download the iOS or Android app from your app store.
   • Sign Up to create your TankMate account.
5. Using Your TankMate Sensor
   • The default sensor reading frequency is 2 times per day (every 12 hours). This can be customized in the app: Settings > Sensor Settings.
   • The sensor will send data online via your Wi-Fi network.
6. Step 4: Note
   • There is no direct connection between your mobile phone and the sensor.
   • To get a reading at any time, use the blue magnet supplied to wake up the sensor. See digital guide (link above).
7. Step 5: Enter Your Tank Dimensions
   • Follow the prompts in the app to select the correct volume, tank quantity, and overflow height. These can be edited later.
   • Multiple connected tanks can be monitored with one sensor, however, the measured volume will only be accurate if the tanks are balanced (keep the same level).
   • The Sensor Height will need to be measured during installation (refer to section 6).
8. Tools Required: Drill (for thicker tank materials).
9. Step 6: Positioning the TankMate Sensor
   • The position of the sensor is critical to ensure accurate readings can be taken. The sensor must:
   • Be at least 100mm above the maximum fill height (overflow height).
   • Have a clear line-of-sight to the water surface. There should be no obstructions.

Dimensions And Positioning the TankMate Sensor

Enter Your Tank Dimensions

• Follow the prompts in the app to select the correct volume, tank quantity and overflow height. These can be edited later.
• Multiple connected tanks can be monitored with one sensor, however the measured volume will only be accurate if the tanks are balanced (keep the same level)
• The Sensor Height will need to be measured during installation. See section 6.

Positioning the TankMate Sensor

The position of the sensor is critical to ensure accurate readings can be taken. The sensor must:

• Be at least 100mm above the maximum fill height (overflow height)
• Have a clear line-of-sight to the water surface. There should be no pipework or other obstructions in the way
• Be at least 300 mm away from the tank side wall
• Not be on a slope greater than 3/12 (15 degrees)
• Be within range of your Wi-Fi network

Tools Required

• Ø30mm hole saw / spade drill bit (poly tanks);
  • OR 30mm diamond core drill (concrete tanks)
• Ø3mm drill bit (poly tanks); OR 6mm masonry drill bit (concrete)
• Power drill / 18V brushless battery drill

• 2 Phillips screwdriver

Tank Preparation And Sensor Height

Tank Preparation

• Drill a Ø30mm hole in the tank lid / roof
• For thicker tank materials (e.g. concrete), ensure that the hole is drilled vertically
• Place the blue rubber gasket onto the tank lid/roof – align the center hole with the 30mm hole you have drilled
• Mark the position of the 4 fixing holes with a permanent marker
• Remove the rubber gasket
• Drill the 4 fixing holes:
  • 3mm for poly tanks
  • 6mm for concrete

Set the Sensor Height in the App

• Use a tape measure to measure the distance from the tank mounting surface (roof / lid) to the floor of the tank
• In the mobile app, open: Settings > Tank Settings
• Set a Sensor Height to match the distance you have just measured (m)
• SAVE the Tank Settings in the app

Install the Gasket and Lens

• Insert the wall plugs (required for concrete tanks only)
• Put the blue rubber gasket back into place – check that it is aligned with the center hole and fixing holes
• Insert the white plastic lens, with the rubber O-ring facing up

Important: Press the READ button underneath the sensor before fixing it down onto the tank. Check the LED status:

• Blinking green, then solid BLUE: connected to the network
• Blinking ORANGE: ready to be positioned (10 sec.)
