LockNLube BTX Inline Meter
SKU: LNL81760
Accurate, easy-to-read fluid metering for your BTX system.
The LockNLube® BTX Inline Meter brings precision measurement to every fluid transfer. Designed to pair perfectly with the BTX Battery Transfer Pump, it monitors the exact amount of oil, ATF, coolant, or DEF dispensed in real time. With a large backlit digital display, sealed body, and rugged build, it delivers reliable accuracy in any shop or field environment.
The four-digit LCD tracks batch and total volumes in either imperial or metric units, allowing you to monitor output and control inventory with confidence. The meter installs inline between the BTX dispensing gun and hose using standard ½-inch fittings, and operates on a replaceable 3 V lithium coin battery for long service life.
Compact, cordless, and maintenance-free, the BTX Inline Meter makes every transfer more efficient—saving fluid, reducing waste, and improving accountability across your operation.

LockNLube BTX Inline Meter
Simple, Accurate, and Built to Last
The BTX Inline Meter uses proven oval-rotor technology for exceptional repeatability and accuracy within ±2 % of reading. The sealed IP65 housing protects against dust, oil, and moisture, making it ideal for shop or outdoor use. A resettable batch counter lets you measure each fill, while total and lifetime counters help track long-term fluid usage.
The backlit screen activates automatically when fluid begins to flow and sleeps after a few seconds of inactivity, conserving battery life. Designed for quick installation, it connects to any BTX system without special tools or calibration. When paired with LockNLube® BTX pumps, it completes a closed, spill-free system that keeps your operation clean and precise.
