The Hoffer Ultrasonic flow meters of the Transi-Flo I single beam and dual- beam type series are intended for flowrate measurements of conductive, non-conductive and aggressive liquids. Ultrasonic flow meters operate on the principle of measuring the difference in transit times of ultrasonic waves traveling in and against the fluid flow direction. The meter consists of a flow sensor and associated electronic unit. Ultrasonic flow meters offer excellent user value and high measurement accuracy over a wide range of flow rates, long-term stability, negligible pressure losses and the capability of measuring the flowrate of virtually any liquid medium. The electronic unit supplies power to both ultrasonic probes and, via its outputs, communicates the flow-rate data to other data processing systems. The meter can be supplied either as an integral system or with a remote electronic unit. The meters are offered in three configurations: SELECT (including a display unit and control keyboard, signal outputs), CLASSIC (including a display unit, signal outputs) or EFFICIENT (signal outputs only). In the integral version, the electronic unit is mounted in an aluminum housing and in the remote version it is fitted into a
