Disinfecting the ozone

The ST80 Thermal Flow Meter Series from Fluid Components International provides precision air/gas measurement to help optimise the ozone disinfection process.

The series is available in either insertion or inline configurations, is well suited for air or gas line flow measurements in various water treatment plant applications. It operates over a wide flow range of 0,07 to 305 NMPS, is factory calibrated, and can provide a flow turndown range of 2:1 to 100:1. With its built-in temperature compensation, the flow meter offers highly repeatable performance under various process environments. It features accuracy up to ±1 per cent of reading with ±0.5 per cent repeatability over variable process temperatures and pressures in line sizes from 6 mm and up.

The ST80 Flow Meter’s thermal dispersion flow sensor design does not utilise any moving parts because its solid-state platinum RTD sensors are precision matched and embedded in equal mass thermowells.

The series features scalable dual 4-20mA outputs as standard and are user assignable to flow rate or temperature. The ST80 series is available through AMS Instrumentation & Calibration.
