Temperature limits of heat conveying liquid:
32…194° F (0 1…90° C)
Custom-made, wall-mounted electronic unit:
32…266° F (0 1…130° C)
Length of the connecting cable between the flow sensor and electronic unit:
4 ft (1 2 m)
Custom-made:
8 ft or 16 ft (2 5 m or 5 0 m)
Maximum admissible working pressure (nominal pressure PN):

If the flow rate exceeds the maximum value q
s
:
• When the flow rate < 1 2∙q
s
, the flow rate measurement and calculations are continued;
• When the flow rate > 1 2∙q
s
, calculations are performed using flow-rate value 1 2∙q
s
, the error “exceeded maximum flow
rate” is recorded and the duration of that error is calculated
