The ECHO Arrow Hunter PLUS Version 3 range of non-invasive flowmeters utilize Transit-time ultrasonic technology for the accurate flow measurement of clean or dirty liquids and liquefied gases in full pipes.

The Arrow Hunter PLUS – FIXED Version3 (AH+FX) is designed for permanent installation on applications where advanced options and configurations are required.The flowmeter includes a variety of input and output options for diverse measurement requirements.

The measurement of flow is based on the principle that sound waves are influenced by a flowing medium. Measurements are made by penetrating the pipe with ultrasound and measuring the frequency variations and phase shifts of the signals received.This measuring technique has no effect on the flowing medium.There is no pressure loss in the pipe and no wear on components of the measuring device.

Theultrasonic sensors are clamped onto the outside of the pipe, thus eliminating the need to dismantle the pipe work and interrupt the process.The AH+FX can be applied to any type of metal or plastic pipe with or without a liner carrying clean or dirty liquids.We have several transducers to chose from depending on pipe size, process temperature and required approvals.

The Arrow Hunter PLUS – FIXED FULL SPEC Version 3 (AH+FS) offers dual channel and Energy measurement capabilities.

ECHO Process Instrumentation offers a 60 day Performance Guarantee!
