Reclamation has developed several prototypes which facilitate the installation of low-cost automation projects.

Prototype 1 - Water Level Sensor

This device uses a float-and-pulley system that is geared to a potentiometer to measure water level. It is designed for use in a stilling well. It can be a useful sensor for a low-cost flow-monitoring station.


Prototype 2 - Gate Position Sensor (With Limit Switches)

This device uses an enclosure over the gate stem to house a potentiometer (to measure gate position) and limit switches. It is designed for a gate system where the stem moves up and down in tandem with the gate.

Because the device is visually prominent, it may not be appropriate for facilities that are susceptible to vandalism. It may not be useful for a system with a webcam, because the enclosure covers the gate stem (a useful visual monitoring point). This device can be a useful sensor for a low-cost gate actuator.


Prototype 3 - Gate Position Sensor

This device is designed for a gate where the stem does not move up and down. On this device a gear reduction box is attached to the gate stem with a chain and sprocket. The gear reduction box is attached to a disk which adjusts the potentiometer and triggers the limit switches.

This device is more appropriate than Prototype 2 where vandalism may be a problem or where there is a need for a webcam. On the installation pictured left, both Prototype 3 and a 12-VDC motor are attached to the brass lift nut assembly of the gate hoist.
