3-30 ADS Portable FlowShark Pulse Manual
When using the water-ultrasonic velocity/combination sensor with
the integrated pressure cell, do not operate the transmitter without
the filter installed.
Removing the filter connector from the sensor connector will
automatically lock the filter connector. While a locked connector
prevents water from entering the sensor, it also disrupts air
pressure compensation. This inhibits the pressure cell from
accurately measure depth.
Make sure the air compensation hose is not hanging in the flow,
blocked, or exhibiting sharp bends. The filter must receive
continuous, unhindered air flow.
2-Wire Sensors
The Portable FlowShark Pulse supports external 4 – 20 mA 2-wire sensors for
measuring depth. The supply voltage for the sensor is 16 volts. Contact an ADS
representative for assistance in selecting an appropriate external sensor. Pre-
configured cables are available in 33-, 66-, and 98-foot (10-, 20- and 30-m) lengths.
Connect the external depth sensor to port 3 on the unit.
