Page 20: How To Use Model With An Elbow Flange
Azbil Corporation 3-3 : How to use model with an Elbow Flange When no weir plate can be installed on the downstream side of a detector, use a model with an Elbow flange. (a) The water level (+ 7mm) can be adjusted since the elbow flange length can be changed. -
Page 21: How To Use The Dummy Detector
Azbil Corporation 3-4 : How to use the Dummy detector The measurable flow rate can be doubled, tripled, or quadrupled by installing 1,2,3 dummy detectors, respectively. A detector must be combined with dummy detectors of the similar shape. If the flow rate is to be increased in future, the measurable range can be expanded easily by installing a model with an elbow flange. - Page 22 Azbil Corporation MagneW PLUS+ Electromagnetic Flowmeter Open channel Flowmeter Detector...
