Two open collector outputs suitable for driving
DC solenoids or external relays. The outputs can
be programmed to provide high and low flow
alarms or pulse output and low flow alarm.
200mA. 30VDC maximum.
9-28 Volt at 4mA maximum.
Lithium battery.
1ms if CAL0 = 2 (unscaled pulse output).
If CAL0 = 1 (scaled pulse output) the duration
of the pulse automatically adjusts to the output
frequency:
a. 1ms if output > 50Hz.
b. 10ms if output = 5...50Hz.
c. 100ms if output < 5Hz.
Operating temperature: -20°C to 60°C.

41mm (1.6") deep (cable glands not included).
Sealed to Nema 4X or IP67 standards.
By cable glands.
Universal mounting bracket supplied as standard.
A galvanised metal bracket is available which
enables the Model 202D to be attached to
a 2" vertical or horizontal pipe.
An optional mounting stem is available for
mounting the Model 202D directly on turbine
flowmeters which have a 1" NPT boss or 1" BSP
boss.
Supplied with mounting brackets.
