8.3 Load
Standard version: ≤ 500 ohms
Explosion-proof version: ≤ 500 ohms
HART ® minimum load: > 250 ohms
8.4 Damping
Programmable from 0 to 60 seconds
8.5 Low flow cutoff
The low flow cutoff can be set to values between 0 and 20% using the software. The set value refers to
the upper-range value. If the measured value is lower than the set volume, the flow rate will set to 0.0
(lb/m, kg/h). This results in the analog output being set to 0/4 mA, and the pulse output will stop generat-
ing pulses.
