Industrial sensing
Level sensing that never touches the media.
The TLV Sensor reads liquid level with optical time-of-flight — no probes, no floats, no fouling. It wires into the PLC you already run and ships from our shop in Albany, Oregon.

Featured product
TLV Sensor — Tank Level Vision
Point it at the surface, wire the current or voltage analog output your controller expects, and read level on your existing PLC or SCADA. The TLV measures using optical time-of-flight from outside the tank, so there's no probe or float sitting in the media to corrode or wear out.

Why Flatrock
Engineered to replace your legacy hardware.
Drop-In Integration
Standard analogue outputs — 4-20mA, 0-20mA, 0-5V, 0-10V — that your PLC and SCADA already speak. No gateways, no drivers, no integration headaches.
Built to Hold Up
Industrial-grade enclosures and conservative electronics, designed for washdowns, vibration, and dust — not the lab bench.
Supported for the Long Run
Two-year warranty, firmware updates, and a support line answered by the people who designed the board.
Made in Albany, Oregon
Designed, built, and tested under one roof.
Housing, electronics, firmware, software — all of it comes out of our shop in Albany, Oregon. Every sensor is assembled and tested by the team that designed it, which is why we can stand behind a two-year warranty and answer support questions without a script.
Where it works
One sensor, a lot of tanks.
Tank Farms & Storage
Continuous level on water, fuel, and chemical storage — no probe in the product.
Food & Beverage
Non-contact sensing over open vats and CIP-washed vessels.
Agriculture & Water
Irrigation reservoirs, wells, and treatment basins on standard 4-20mA loops.
