Liquid/bulk material fill level measuring device for use in motor vehicle tank, has transmitter and receiver in the form of piezo-foils, where device is formed as dip senso, and foils have length of fill level range that is to be detected

摘要

The device has a transmitter and a receiver in the form of piezo-foils (1, 2), where the device is formed as a dip sensor. The foils have a length of fill level range that is to be detected. An ultrasound signal emitted by the transmitter is controlled by a sound transmission media for the receiver. A connection is made between the transmitter and receiver piezo-foils that are provided in a pile, by a double-sided adhesive strip.
