USTDII Magnetostrictive Liquid Level Gauges - USTDII

USTDII Magnetostrictive Liquid Level Gauges

Product Overview

The Level Plus(R) Model USTD II level gauge is designed for use in Underground Storage Tanks (UST). The most common UST application is containing automotive fuels at gas stations. The Model USTD II transmitter provides 3-in-1 measurement using one process opening for product level, interface level, and temperature measurements. Once the transmitter is installed and calibrated, there is no requirement for scheduled maintenance or recalibration.

The Model USTD II level gauge uses a proprietary ASCII based protocol referred to as Direct Digital Access (DDA) for communication. The DDA output utilizes a 4-wire, multi-drop power and data bus RS-485 network. Utilizing the data bus network eliminates requirements for individual cable runs to and from each tank. The RS-485 network also allows for longer cable runs for more tanks and greater distances.

Magnetostrictive Principle

Level Plus gauges are based on the magnetostrictive measuring technology, which is successfully used for more than 30 years at MTS. Magnetostriction is a combination of magnetic (non contact) and ultrasonic effects (speed control). According to MTS know-how, two magnetic fields interact, and a torsional strain pulse on the sensor element results. The running time of the the pulse is used to determine the level measurement with a high degree of accuracy and reliability. All Level Plus Tank Gauge systems base on this principle, which ensures a really innovative and promissing measuring system for continous level measurement
