EtankNet the system

EtankNet system overview
For illustration purposes only

The Pebble device supports up to two sensors, so you can set up:

  1. Two separate tanks (A and B).
  2. A main + reserve pair (main on Sensor A, reserve on Sensor B).
  3. A single tank split by a wall (Sensor A above main section, Sensor B above reserve section).

Important: In any main/reserve setup, Sensor A is always the main and Sensor B is always the reserve.

Start by entering the main tank dimensions: choose Square/Rectangle, Vertical Cylinder, or Horizontal Cylinder.

  • Measure inside dimensions (length, width, radius/diameter, and height).
  • Record the overflow height (use full height if there is no overflow).
  • Mount the sensor above the overflow and record the sensor height.
  • If you want usable water (not just total), enter the foot-valve to floor distance.

If the tank has a reserve partner, create the main on Sensor A first, then the reserve on Sensor B.

Add a Tank

Start by entering the main tank dimensions: choose Square/Rectangle, Vertical Cylinder, or Horizontal Cylinder.

  • Measure inside dimensions (length, width, radius/diameter, and height).
  • Record the overflow height (use full height if there is no overflow).
  • Mount the sensor above the overflow and record the sensor height.
  • If you want usable water (not just total), enter the foot-valve to floor distance.

If the tank has a reserve partner, create the main on Sensor A first, then the reserve on Sensor B.

Add a main tank:

Log in to Add a Tank
Main tanks must be created on Sensor A.

Optional add a Reserve tank or section:

Log in to Add Tank Reserve
Reserve tanks/sections belong on Sensor B.

Add a Tank Object

Some tanks have extra bays or solid structures that change capacity. Model these as Tank Objects.

  • Add – External voids that hold water (sumps, side bays).
  • Subtract – Solid intrusions (ramps, blocks, equipment).

Before you can add objects: edit the parent tank and check Has additional tank measurements. Then go to Add a Tank Object (A or B) to attach objects to the correct sensor’s tank.

Optional add tank Object to Main tank:

Log in to Add Tank Object
Make sure the parent tank has “Has additional tank measurements” enabled.

Optional add tank Object to Reserve tank:

Log in to Add Tank Object
Objects for reserve tanks should be added under Sensor B.
