Echo thickness gauge Multigauge 4000 Series
Echo thickness gauge with multiple echo / ROV applications / for extreme conditions under water / used up to 4000 m under water / IPR and AMVs

The Multigauge 4000 series is an echo thickness gauge which is available in two versions and is designed for all ROV applications. The first version is the echo thickness gauge Multigauge 4100, which can be applied to depths of 1,000 m. The echo thickness gauge Multigauge 4400 however finds its tasks in up to 4000 m depth. Each underwater ultrasonic thickness gauge has been specially designed for harsh environmental conditions and can therefore be used in every branch of industry. Continue to operate the underwater ultrasonic thickness measurement of Gert multiple echo technology, can take place so that thickness measurements without any previous layers have to be removed. Additionally, there is an RS232 interface which makes data transfer easy. Other technologies are IPR (Intelligent Probe Recognition) and AMVs. IPR is on one device automatically increased performance and AMVs guarantees that only meaningful measurement results are displayed, even on badly corroded metals. Here you will find an overview of all underwater ultrasonic thickness gauge (s)..

More information on the threefold echo-technology

Depending on the material to be measured, each underwater ultrasonic thickness gauge should be calibrated at different sound velocities. Paints have different sound speeds as metals, it is necessary to ensure that these do not affect the measurements. The 3-echo technology guarantees that all coatings have no effect on the measurement.
 

This is how the measurement of the echo thickness gauge works

A transmitted ultrasonic pulse is sent through paint and metal and is reflected by the rear wall. The returning echo reverberates in the metal and only a small part of the echo returns through the coating. The time between the small echoes gives us the time of the echo within the metal, this time is in direct connection to the material thickness. The underwater ultrasonic thickness gauge interprets the recurring echoes automatically and calculates the thickness of the material. A minimum of three echoes is checked each time. This is called Automatic Measurement Verification System (AMVs).

ROV Messfühlerhalter
Das Echo Dickenmessgerät kann mit einem Messfühlerhalter ausgerüstet werden. Dieser ermöglicht es, den Messfühler auf der zur messenden Oberfläche zu montieren ganz egal ob diese flach oder uneben ist. Das Design macht es möglich, dass sich der Messfühler vom Echo Dickenmessgerät um 75° in alle Richtungen bewegen kann. Der Messfühler wird einfach in die Haltevorrichtung gesteckt ohne dass er die Oberfläche des Gegenstandes berühren muss. Die Messung findet dann dank Ultraschallmessverfahren kontaktlos statt.
