Leak Detection and Inventory Control Probes

Features/Capabilities

Features

• Easy to use and install.
• Uses innovative, magnetostrictive position measurement technology to report liquid levels.
• Highly stable performance.
• Unparalleled accuracy and performance when used with Franklin Fueling Systems Automatic Tank Gauge.
• Screw-in electrical connector provides quick installation or removal eliminating the need to resplice wires.
• Intrinsically safe circuits for hazardous locations.

Theory of Operation

• An electromagnetic field is created inside the probe head and forms around a long waveguide within the probe shaft when position measurements are taken.
• The electromagnetic field interacts with the magnetic field of the float(s) and produces a shock wave in the waveguide that travels at a known speed.
• When the shock wave is detected at the probe head, the probe creates a signal that corresponds precisely to the product level.
• Product expansion calculations are enabled by temperature sensors that are located at various points in the probe shaft.

Capabilities

TSP-LL2 Leak Detection Probe:

• Can report the level of one, two or three (Density) floats.
• Capable of precise leak detection, density measurement, inventory control and reconciliation.

TSP-LL2-1 Inventory Control Probe:

• Can report the level of one or two floats.
• Capable of precise inventory control and reconciliation.

Installation Kits:

• Use the appropriate FFS suspension style installation kits to install all TSP-LL2 leak detection probes.
• Use the appropriate FFS bottom mount style installation kits or approrpriate riser cap with compression gland to install all TSP-LL2-I inventory control probes.
• TSP-LL2-I probes include special hardware to allow them to rest on the tank bottom.

Applications

The INCON LL2 series of liquid level probes feature exceptional linearity, resolution and stability and are used in underground storage tanks (USTs) and in aboveground storage tanks (ASTs). Two types of probes are manufactured for use with the Tank Sentinel® Automatic Tank Gauges (ATGs).

• The TSP-LL2 probe is used for UST and petroleum applications.
• The TSP-LL2-I probe is used for AST and inventory only applications.
• Probes are available in many sizes that are suitable for all common tanks.
• The TSP-LL2-I probe is used for AST chemical or waste oil applications (all wetted parts of the probe and float are made of #316 stainless steel).
• Easily installed into 4 inch riser pipes or optionally into 3 or 2 inch riser pipes (with reducer fitting).
