• The flow monitor detects the flow rate of water,
• shows the current flow rate on its display,
(max. value displayed: final value of measuring range + 20%)
• and generates 2 output signals according to the set output
configuration.
Analog output
(only output 2)
switching function
(output 1 and output 2;
function can be selected for
each output separately)
output polarity (applies to both
switching outputs)
Application: water.
(please see the maintenance details on page 23)
• For seamless precision steel to DIN 2391/1 and T-pieces to
DIN 2353.
• Adjustable to T-pieces with nominal diameter of 15mm, 19mm or
24mm.

For nominal diameter 19 and 24, 1/10 of the LPH value is displayed.
The displayed value must be multiplied by factor 10.
Example: displayed value = 98; real value = 98 * 10 = 980 LPH
