INSTALLATION It is forbidden to wire signal cables nearby (less than 5 cm) with power cables or cables of other devices. It is forbidden to change length of a cable about temperature probes Factory-installed temperature sensors do not split, shorten or extend the cables. Calculator can be mounted in several different ways: - Wall mounting, without possibility sealing of mounting - Wall mounting, with possibility sealing of mounting - Mounting on standard DIN-rail - Panel mounting - Direct mounting on ultrasonic flow sensor housing, turning every 90o (only when the temperature of the flow does...

Panel mounting on standard DIN-rail Adapter plate according to EN1434-2:2007 for wall mounting of calculator (if the aperture in the wall is too large for the calculator) The manufacturer guarantees only English text available on our web site: www.isoil.com

MOUNTING OF FLOW SENSORS - For flow sensors DN15…DN32: no requirements for straight pipeline length in upstream and downstream directions. - For flow sensors DN40…DN50: upstream straight pipeline length must be not less 5DN and downstream straight pipeline length must be not less 3DN Avoid the flow sensor installation near after the pumps which can cause cavitations. Flow sensor can be mounted both vertically and horizontally in pipelines. Vertically mounting of the flowmeter is allowed only if flow direction in the pipeline is from down to up. The direction of the sensor installation (is indicated...
