Troubleshooting
PROBLEM SOLUTION
Transmitter indicates a
current of 0 mA Check the wiring for an open circuit. An open circuit is the most common issue
with a 0 mA signal
Transmitter jumps to a
current reading between 19
and 20 mA Check the installation of the transmitter. Bad installation fittings will cause false
signals near the top of the tank, which typically translates to a signal between 19
and 20 mA. Also look for interference just below the transmitter. If the transmitter
is installed in a metal fitting, switch to a plastic fitting.
Transmitter indicates a
current over 23 mA Immediately check the wiring for a short circuit. The EchoSonic II is current
limited to 22 mA. Anything above 23 mA indicates a short circuit.
Transmitter always jumps to
LOST condition Check the dimensional configuration (Height and Fill-H) of the EchoSonic II.
Make sure that the Fill-H setting corresponds to the full level of liquid (from the
bottom up) and not the distance from the transmitter to the liquid (top down).
Output of transmitter is
opposite of the level of
liquid Check the Output at Empty Setting. Make sure the setting is correct (4mA at
bottom or 20 mA at bottom).
No Unit Detected in
WebCal WebCal cannot detect an EchoSonic II connected to the computer.

Check that the Fob is connected to the USB port.

Check that all four wires (Red, Black, White and Green) are securely attached
to the Fob.

Check in Device Manager that both drivers (WebCal Configuration &
EchoFob) are present.
Internet error. The server

be resolved. This is a warning indicating the computer configuring EchoSonic II is not
connected to the internet. Click OK to continue. Flowline recommends being
connecting to the internet for all configurations. Not being connected to the
internet will not prevent the EchoSonic II from being configured.
Cannot access some of the
features in Configuration As choices are made in Configuration, WebCal will begin to eliminate functions
that are no longer active. To reset Configuration or get access to all the features,
