ORIFO METER HDT series Multifunction Digital Flowmeter OUTINE HDT is a new series Oriflo meter combining orifice plate with multidigital indicator. HDT detects differential pressure exerted by flow velocity on the orifice plate and displays it digitally as flow rate. Available meter sizes range from 15m to 3mm dia. The principal applications are hot and cooling water, air flow measurement and so forth. FEATURES Excellent cost performance Flow rate measurement is possible at low cost for medium or large diameter pipes. Compact design The indicator part is very small and saves mounting space. Easy installation Available various process connections of Screw, Flange, and Wafer to meet all field possible requirements and for easy pipe installation. Applicable for both parallel and vertical pipes. Various functions of indicator Any type can be chosen out of the following: Battery type, Current output type (2wire 42mA DC), Alarm output type, Temperature sensor input type and onworks type Indicator part is interchangeable Easy to see because of large CD display MAIN APPICATIONS Air conditioner water and air line Cooling water line General process line in medium and large diameters Sewage disposal process Pure water device Fire pump performance test Blower performance test INDICATOR SPECIFICATION Refer to the DT series TECHNICA GUIDANCE TGEM125E for the details of digital indicator.

If actual fluid condition has different values, conversion calculation is required per following formula: Qw =Qx γ Qw : Water converted flow rate Q : Flow rate of actual fluid γ : Density of actual fluid (g/cm 3 ) The calculation of figures in the above flow range table has been made on the premises that SGP, a JIS code name for a carbon steel pipe for ordinary piping, is used for main pipes. In case of pipes other than SGP, multiply the above liquid quantity by (the inner diameter of a pipe used the inner diameter of a SGP pipe) 2. Full scale ranges for gas of upper table are shown by the flow rate of AIR, at, 1atm. If actual fluid condition has different value, conversion caluculation is required per following formula.
