Manual readings
A staff gauge read in the field, with gaps between one visit and the next.
Point-in-time data.HydroTube is our compact device for measuring level and flow in open channels using a stilling well.
The sensor sits submerged and protected, the electronics live under an IK10 dome, and the data goes out over LoRaWAN, 4G, or satellite. Batteries last 1 to 3 years.

In irrigation canals, conveyance channels, and process channels, level is read off a staff gauge and flow is reconstructed after the fact. Between visits, nobody knows what happened.
A staff gauge read in the field, with gaps between one visit and the next.
Point-in-time data.Exposed sensors that get fouled or hit by floating debris.
Unreliable readings.Channels far from the power grid, with patchy or no cellular coverage.
Data stuck on site.Vandalism, theft, impacts, and animal trampling on equipment exposed to the elements.
Short-lived equipment.A rugged tubular body that installs inside the stilling well. Whatever wears out can be replaced without dismantling the installation.

Withstands impacts, including animal trampling, and houses the communications antenna.
Encapsulated electronics and batteries, which come out for maintenance or replacement every 1 to 3 years.
Inside the stilling well, away from sediment and floating debris, with a reel to adjust the depth.
Stainless steel, fixed to the ground with ¼ × 1¾" anchor bolts to guard against tampering and theft.
HydroTube measures level. At a gauging section with its rating curve, that level is converted to flow.


Reading interval, communications, and cable length are set to suit the channel and the system that receives the data.

It measures level. At a gauging section with its rating curve, that level is converted to flow.
The sensor sits inside the stilling well, protected from floating debris, and can be replaced in the field.
No grid power needed: it runs on batteries that last 1 to 3 years. Where there is no cellular or LoRaWAN coverage, it transmits via satellite.
With the IK10 dome, the reinforced housing, and the stainless steel plate anchored to the ground.
