Tek-Flex 4100A Explosion-Proof Guided Wave Radar Level Transmitter is based on the Time Domain Reflectometry (TDR) technology. It is a 2-wire guided radar level transmitter that measures distance, level, interface, mass, and volume of liquids, pastes and slurries. Tek-Flex 4100A has stainless steel housing for a corrosive environment and uses a probe to guide a signal to the measured product’s surface; therefore, it can measure under challenging conditions. Its performance is not affected by dust, foam, vapor, heated surfaces, boiling surfaces, pressure, temperature, and density changes. Tek-Flex 4100A Explosion-Proof Guided Wave Radar Level Transmitter is suitable for liquid storage and process applications and is pre-calibrated from the factory for easy installation. Hence it is mostly used in various industries, including oil and gas, chemical, petrochemical, metal, minerals and mining. It has a rotatable and removable transmitter and is arranged with horizontal or vertical housing options for easy access to the device terminals, including an optional display. Continuous level measurement in process or storage tanks, reactors, and pressure vessels is possible using Tek-Flex 4100A Explosion-Proof Guided Wave Radar Level Transmitter.
