Guided Radar Gauge with 2 wire system TGR3000

TGR3000 is a 2-wire continuous level-measuring instrument using micro-pulse reflection. The measurements of the level of liquids, slurries and solids, and the interface of oil and water, etc. can be made. And analog output function is equipped.
The micro-pulse emitted from the level meter propagates along the fixed probe in the tank. And the level of the liquid or solid is measured by measuring the propagation time of the micro-pulse, which is reflected at the surface of the liquid or solid. The velocity of the micro-pulse propagation is hardly influenced by the change in temperature and pressure, so the high accuracy measurement can be made regardless of any change in the measurement condition.
And the loss of micro-pulse diffusion is so little that the measurement of low dielectric liquids and solids can be also made.
Very small flow rate can be covered:  Min. 0 - 0.5 L/h [Water] can be measured.  
 Alarm output option available:    In addition to local indication type, alarm output version is also available.
 Compact design:   Easy installation onto instrument panel.
 Safety for high temperature and pressure: All metallic material construction covers tough applications!
