Flexible Inventory Probes

Whether you are working in a tight, low-overhead space or a high aboveground storage tank, our flexible probes are designed to accommodate your tanks.

A FLEXIBLE PROBE SOLUTION

Like our standard rigid probes, flexible inventory probes provide reliable and accurate inventory management for otherwise difficult installation applications. Available in lengths for tanks ranging from 4’ to 68’ (1,219 mm - 20,726mm). 


Specialized Applications

Flexible probes provide an ideal solution for tall tanks, tight spaces, aboveground, and indoor applications.

Built for Large Tanks

Flexible probe float kits come with product float, water float, and a spacer which ensures accurate readings for these longer length probes.

Easy Installation

The flexible probes come with everything needed to complete an accurate installation in large inventory tanks.

ACCURATE INSTALLATION

The flexible probe installation kit includes several design features which ensure accurate installation in large storage tank applications.

Guide Sleeve

A 16” (406 mm) stainless steel sleeve guides the probe into place and ensures proper vertical alignment.

Variable Height

The adjustable compression fitting allows for variable height adjustment, giving you the ability to set the probe depth with precision.

Consistent Tank Readings

The guides and fitting make sure that the probe is installed correctly, thereby ensuring accurate and consistent level readings.

MADE FOR LARGE STORAGE TANKS

The water and product level float kits are designed specifically to provide accurate inventory levels on flexible probes no matter what the application is.

Accurate Readings

Flexible probes can provide accurate inventory level management for up to 5,875,000 gallon (22,200,000 liters) tanks.

Probe Weight

Each flexible probe comes with a stainless steel probe weight and pin to help keep the probe properly aligned in large storage tanks.

Fuel Options

Float kits are available in 2”, 3” and 4” diameters for both diesel and gasoline float kits are available.

Flex Probes - Aboveground - Wide.psd
ABOVEGROUND STORAGE TANKS

Flexible probes are ideal for aboveground storage tank applications where probes are installed at higher levels.

Easy Installation

The flexibility of the probe allows the installer to take the entire probe to the top of the tank, uncoil it, and then install it.

Avoid Danger at Height

A long rigid probe can be difficult and dangerous to position and install at large heights.

Easy Transportation

Transporting a longer rigid probe takes up significantly more space than a flexible probe.

LOW OVERHEAD CLEARANCE

Flexible probes make installing in spaces with little overhead clearance, like indoor generator tank applications, easy to carry out.

Minimal Install Space

Fitting a rigid probe down into a tank indoors can be next to impossible, unlike flexible probes that can be installed with minimal space required.

Uncoil & Install

A flexible probe can be uncoiled and fed directly into the tank within a small amount of space.

Probe Weight

An included probe weight fits at the bottom of the probe and helps to pull the probe into place.

Operation

When a flexible probe takes a measurement an electromagnetic pulse is created inside the probe and travels down a long waveguide within the probe shaft. When the pulse encounters the magnetic field of one of the floats a portion of the pulse is reflected back to the probe head. When the reflected pulse is detected at the probe head the data is sent to the automatic tank gauge and a precise product level is displayed. Temperature sensors located at various points on the probe shaft allow the automatic tank gauge to compensate for temperature related expansion or contraction of the product.

Ordering Guide

Use the guide and diagram below to determine the maximum probe length based on the dimensions of your tank. Then use the maximum probe length to choose the appropriate flexible probe model from the tables below.

A vertical tank is depicted, however, flexible probes can also be used in a horizontal tank application.
