The Ramsey Granuflow DTR 131 and DTR 231 Flow/No-Flow Detectors are low-cost, non-invasive, microwave-based instruments that detect and monitor flow/no-flow conditions of bulk solids in pipelines, ducts
and air-slides, as well as at transfer points of chutes, conveyor belts and bucket
elevators. The real-time flow information they generate allows you to monitor processes closely and leads to increased
reliability, higher quality end product, reduced downtime and fewer hazards to jeopardize operators and equipment.

The Granuflow GTR 130, a non-contact flow sensor, is ideal for monitoring solids flow in pipelines, ducts, air-slides, and at transfer points of vibrating chutes, conveyor belts and bucket elevators. Some successful applications include the monitoring of roofing
granules being applied to shingles, the flow of ingredients into extruders and mixers,
and the flow of additives into the production of wallboard. Thermo Ramsey has extensive
experience in applying microwave technology in all kinds of applications and various types of industries.
