Canal gates, automated.
A solar-powered, cellular-connected gate actuator for Fresno 6400, 6600 and similar canal gates up to 27 inches. Monitor, control and automate from anywhere.
- 100% bolt-on; just hand tools needed
- Original handwheel and lift remain fully functional
- Accurate gate positioning to 1 mm (0.04 in.)
- Solar-powered with built-in cellular modem
- IP68 actuator rides out temporary submersion

Everything a ditch rider does at the gate, done remotely.
Remote monitoring & control
Live website access from any smartphone, tablet or computer.
Automated flow & level
Maintains your flow or level target unattended as upstream conditions change.
Obstruction detection
Integrated gate obstruction detection and real-time alarms.
Local touchscreen
On-site display for monitoring and control at the gate, with pushbuttons for instant moves.
Open integration
Analog, digital, Modbus and SDI-12 sensor inputs. MQTT for third-party integration.
Fleet dashboard
Manage all your GATERs from a single dashboard on HydroLogik.cloud.
Stop driving gate routes.
See and adjust every gate from your phone, and let GATER hold your flow while your crew works on what matters.
Fewer trips to the gate
Remote monitoring and real-time alarms give live situational awareness without a site visit.
Constant flow, automatically
Compensates for upstream changes and gate clogging to keep flow rates steady.
Accurate, fair deliveries
Prevents over- and under-delivery, helps stop unauthorized diversions, and keeps upstream gates from taking water meant for downstream users.
Safe emergency operation
Operate gates remotely when they are inaccessible or dangerous to visit. On site, the handwheel and lift still work.
Built to fit your system.

Direct lift. No chains, no gearboxes.
The lift is an IP68 rated waterproof industrial linear actuator with 1,125 to 3,600 lb of push/pull force, enough to seat a gate firmly in its stop blocks and pull it back out. There are no exposed rotating parts.
Paired with a flow or level instrument, GATER finds and holds its target: it can keep a lateral delivery steady, or keep an irrigation pond topped up without overflowing as demand changes and weeds clog the gate.
- Adjustable limit switches and a position sensor prevent overdriving
- Built-in clutch and jam detection protect the gate from obstructions
- Multiple GATERs can share one cellular GATER over radio
- Fully reversible: remove GATER and the original operator goes back on
- Manage deliveries from your pickup, the shop, or Hawaii
