Measure true level with this sensor and transmitter
The Signet 2260 Ultrasonic Level Transmitter and the 2270 Ultrasonic Level Sensor (photo) provide reliable and maintenance-free measurement and detection for nearly all liquids and types of vessels — from closed-tank systems to open basins. Suitable for use in a variety of water-treatment, chemical-processing and ultrapure-water applications, these ultrasonic devices offer more intelligence than other level-measurement products on the market, says the company. The devices can differentiate between substances like condensation or agitation and the true, actual level of the medium, thereby avoiding incorrect measurements. The transmitter and sensor have accuracies of±0.05% of the measurement range. Design features include use of a narrow beam that allows safe installation in limited-space tanks and near static objects. The device can recognize foreign matter and disregard them to ensure reliable level measurement, even in tanks where there are vapors, condensation or turbulence. Sensors are available in 4- and 6-m sizes with 1.5- and 2-in. threads. — Georg Fischer LLC, Irvine, Calif.
