Measuring ranges depending on the inner diameter of the pipe
12 Measuring ranges depending on the inner diameter of the pipe
12.1 Determination of the inner diameter of the pipe
Determination of the inner diameter of the pipe: 1. Labeling on the pipe ( e.g. 60.3 x 3.6 results in an inner
12.2 Input of the inner diameter of the pipe
Before the initial operation, please enter the exact inner diameter of the pipe via the keypad of the Data
Display DD109 (see instruction manual Data Display DD109)
12.3 Table max. values of the measuring range inner pipe diameter ¼" to 2 ½"
The Flowsensor FS109 works up to a maximum flow velocity of 607 ft/sec. and is preset to an inner pipe
diameter of 2 inches.
This corresponds to an analogue output 4... 20 mA of 705 SCFM (other units please see table)
