Robust flow indicators simplify machine customisation

SAET is an Italian manufacturer of induction heating machines used to surface-harden components used worldwide in automobile and engine manufacture. The induction heaters themselves require controlled cooling to maintain repeatable performance, and the heat treatment process involves quenching and controlled cooling of the components.

SAET wished to standardise on a single flowmeter style for monitoring and control of the cooling flows, but found that the additives used tended to affect the repeatability of turbine flowmeters, and other electronic meters were too expensive.

However, the Eletta range of differential pressure-based flow measurement systems, available in the UK from Flotech Solutions, offers a standard design of pipework sensor, with different indicators and transmitter styles for use on the various applications needed in each installation. SAET therefore chose the economical V-Series low flow alarm systems, the S-Series with local flow indication on 130mm dial gauges, plus dual set-point alarms and the full analogue output for remote control signals, also with a local indicator, on the Eletta A-Series.

With no need for on-site calibration, high repeatability and excellent reliability, SAET found the Eletta range of DP flow indicators and alarms invaluable in customising machines to meet local requirements, even allowing upgrades on site.
