THE WELL BUBBLER
WWW.WELLBUBBLER.COM
CONFIGURATION: TELEMETRY OUTPUT
The Well Bubbler is equipped with two analog outputs, compatible with PLCs, VFDs,
SCADA and most telemetry systems.
The analog outputs have a range of 0-5Vdc and 4-20mA. The scaling of those outputs
is defined by the value of the Telemetry Output parameter, as follows:
Water Level (feet) = ( Vout / 5.0) * Telemetry Output (feet)
Water Level (feet) = ( mA – 4.0 ) / 16.0 * Telemetry Output (feet)
Set this parameter to the maximum water level value you expect to measure, or simply
to the rating of the Bubbler itself.
For example, setting the Telemetry Output to a value of 500 will result in a 5.0V and
20mA analog output, when the water level reaches 500 feet.
Note that the analog outputs are updated when the Well Bubbler has sampled the well
level - once per measurement period. The analog outputs will maintain the last known
value between samples.
