Ultrasonic Liquid Meters UVR-011/UVR-T Equipped with Electroacoustic transducers.

                

The electroacoustic transducer of the clamp-on type (ЕАT – 303Н) or inserted type (EAT ТХ-206), which are equipped with ultrasonic liquid meters UVR-011/UVR-T, is designed to convert an electrical pulse into an acoustic signal and vice versa in ultrasonic liquid meters. Ultrasonic liquid level meters UVR-011/UVR-T are equipped with clamp-on or inserted transducers, which are mounted in pairs on one or two pipelines. Clamp-on (ЕАT – 303Н) transducers are mounted on the outer surface of the pipeline and can be equipped with magnetic clamps, while the inserted type (EAT ТХ-206) transducers are placed in the holes made in the pipeline walls. EATs are passive – they do not have built-in batteries and energy storage. The set of clamp-on EAT ТХ-206 sincludes: one pair of clamp-on, one pair of EAT mounting brackets and one pair of TSP heads. The set of clamp-on EATs -303Н  includes: one pair of surface-mounted EATs, one pair of EAT mounting brackets and one pair of connectors. EATs are supplied to the Customers only in combination with UVR-011/UVR-T or only as spare parts for previously supplied ultrasonic liquid meters UVR-011/UVR-T.

The main technical characteristics of EAT are given in the Table.
