INTRODUCTION This manual is integral part of the product. Read carefully the instructions contained since they give important indications for the safe use and maintenance. Technical information and relative products in this manual could undergo modifications without any previous notice. The flow meter must be used for what it has been built for.
TECHNICAL CHARACTERISTICS ELECTRIC CHARACTERISTICS Classification of the instrument: class I, IP 67, category of installation II Power supply Power supply current Pmax versions voltage 18÷30 Vdc 10 W INPUT/OUTPUT ISOLATION Input/output are insulated up to 500V The output 4÷20 mA and the output 24 Vdc are electrically connected ENVIRONMENTAL CONDITIONS OF USE The instrument can be installed inside or outside buildings Altitude: from –200 a 6000 m (from -656 to 19685 feet)
ELECTRICAL CONNECTIONS GROUNDING INSTRUCTIONS For the correct operation of the meter it’s NECESSARY that sensor and liquid are equipotential, so ALWAYS connect sensor and converter to the ground CONVERTER POWER SUPPLY before connecting the power supply, verify that the mains voltage falls between the limits indicated on the tag plate ATTENTION: the converters on dc power supply line are not protected against the inversions of polarity.
