FLOWCERT LITE (UL) INSTRUCTION MANUAL

Relay Outputs
The five relays can be programmed for a variety of alarms, pump control, or
other process functions. The relay contacts are all rated at 5A at 240V AC. All
connections should be such that the short circuit capacity of the circuits to
which they are connected, is limited by fuses rated so that they do not
exceed the relay rating.
Current Output
This is an isolated (floating) mA output (to 150 V), of 4 - 20mA or 0 - 20mA,
and the load should not exceed 500

.
Temperature Input
The FlowCERT Lite can be used with an external temperature sensor and a
dB3 transducer, allowing more localised compensation of the measured
distance due to changes in temperature
.
There are 2 types of external models, Type A and Type B and their ranges are
as follows:
TYPE RANGE
A -25° to 50°C
B -25° to 125°C
Important Information
The temperature sensor should be placed close to the point of measurement
and out of the effects of direct sunlight. This allows for the temperature sensor
to measure the true air temperature, thereby giving the most accurate results.
