There are two basic types of procedures used for obtaining a gauge reading—innage and outage (dip and ullage). For the innage method, the gauge reading shall be defined as the measure of the linear distance along a vertical path from the datum plate or tank bottom to the surface of the liquid being gauged.

e Introduction te rn Standard, a manual measurement by dip tape (hand dip) is performed as an innage dip to the datum plate of the tank. The level value is obtained by subtracting the ullage value from the upper reference value.

Innage gauging (also referred to as bottom gauging or dip gauging) measures the distancefrom the datum (strike) plate (or the bottom of the tank if there is no datum plate)to the surface of the product.

A dry dip (ullage) measures the space between the liquid and a reference point at the top of the tank. You perform this type of dip when the product is too thick to be accurately measured.

A dip tape is a manual user-operated liquid level measurement device, which consists normally of some form of calibrated tape, for example, meters, feet, yards, with a weight attached to the end.

Nov 4, 2019 · Alternate Ullage Gauge – The ullage obtained by subtracting the measured height of the liquid in the tank from the official reference height of the tank. Innage Gauge (Dip, Sounding) – The height of the liquid surface from the bottom of the tank (or datum plate).

The HERMetic DIP Type 2 GT ensures closed tank bottoms are dry post-crude oil washing. It includes a graduated weight and stainless steel tape with metric and inch scales. It operates without vapor escape and estimates tank bottom distances accurately.

UTI (Ullage Temperature Interface) is a detector used to measure the ullage, temperature, and the oil-water interface onboard tankers. On this page, we examine the UTI functions, principles of working and the importance of its annual calibration.

The document provides specifications and operating instructions for an intrinsically safe triple function gauging tape for measuring ullage, oil/water interface, and temperature in restricted applications.

Dipsense specializes in ullage temperature interface instruments sensors aka UTI sensors. Its mission is to provide the highest quality products to fully satisfy the maritime portable tank level monitoring needs on tanker ships.
