CDT1000 series QUICK FLOW. Digital Flowmeter for Air Conditioning Application OUTLINE FEATURES STANDARD SPECIFICATION

Transcription

1 QUICK FLOW CDT1 series Digital Flowmeter for ir Conditioning pplication OUTLINE CDT1 is a new series of flowmeter which combines a multidigital indicator with a pitot tube. CDT1 detects the differential pressure exerted by flow velocity in the pitot tube inserted in the pipe and s flow rate with digital indication. pplicable sizes range from 2mm to 4mm dia. The principal applications are for hot and cooling water lines for air conditioning in apartment and office buildings and other facilities. FETURES Easy installation Installation simply by making a 5mm dia. hole and welding 2mm (/4") socket at measuring point of existing pipes. This is most convenient for renewal use when additional flow sensor is required on the line. Low pressure drop Wide measuring range Measuring range selectable depending on application pplicable for both horizontal and vertical pipes. Various indicator functions selectable from the following: Battery type, Current Output type (2wire 4 to 2m), larm Output type, Temperature Sensor Input type and LonWorks type Indicator parts are interchangeable.
