USE3000 and USE6000 Tank Level Transmitter from Barksdale

USE3000 and USE6000 Tank Level Transmitter from BarksdaleThe Barksdale Tank Level Transmitters are sensors for remote indication level of liquid media. They operate according to the float principle with magnetic transmission (Permanent magnet, Reed switch and resistor chain). The liquid level is indicated on indicating instruments connected to the sensor. 

The USE3000 provides a max. length up to 3000 mm.

The USE6000 provides a max. length up to 6000 mm.

USE3000 and USE6000 Tank Level Transmitter Q & A

+ What exactly does this tank level transmitter measure and how?
It measures the liquid height inside a tank (up to 3000 mm in this version) using a float principle with magnetic coupling (permanent magnet, reed switch + resistor chain) to translate the physical float movement into an output.
+ What materials is it made of? Can I choose between options?
Yes — available in stainless steel or brass versions.
+ How can it be mounted? Are there orientation or installation constraints?
Mounting can be “from the top” or “from the bottom,” with a mounting angle tolerance of ±30°.
+ Which liquids / applications is this suited for?
Good for tank level monitoring of liquids in: tanks, open containers, fuel & oil tanks, service & wastewater applications.
+ What’s the accuracy / repeatability like?

The specification emphasizes “high repeatability,” meaning once calibrated/setup it reliably reproduces the level reading — important if you need consistent monitoring.
