Franklin level gauge probe


Product parameters

TSP-LL2 level gauge rod is an advanced measuring equipment. It uses Magnetostrictive Position Measurement Technology and can accurately report the stock in storage tank.


Easy to use and install

Using Advanced Magnetostrictive Technology

High stability performance

Helical locking electric signal connection plug for easy installation and disassembly

Intrinsically Safe Circuit Design


TSP-LL2 probe rod is composed of a main pole and one or more magnetic float components. The float can slide freely on the main pole. The probe bar uses advanced magnetostrictive technology to realize the measurement function through the position of the float and several liquid levels.

The probe rod can record the position of the magnetic float.

TSP-LL2 probe bar has accurate side leakage monitoring and inventory monitoring functions

Use TSP-K4A or TSP-K4AS mounting components on 4-inch support risers


INCON LL2 series level bar has excellent linearity, accuracy and stability, and is suitable for underground and ground tanks. Both kinds of probe rods can be used in INCON liquid level instrument console.

TSP-LL2 rod for measuring underground tanks and petroleum products

TSP-LL2-I bars can be used for overground tanks and only for inventory measurement

Many rods of different lengths are suitable for all general purpose tanks.

TSP-LL2-I probe can be used for chemical or waste oil products in overground tanks (all immersed parts on the probe are made of 316 stainless steel)

Very easy to install in 4-inch, 3-inch or 2-inch risers
