Direct Read Cable Assembly Installation
When installing using a Direct Read Cable Assembly, the Levelogger can be
deployed before it is programmed and started with the software. The Levelogger
is installed using a Direct Read Cable to a Direct Read Wellhead, where a PC
Interface cable is connected allowing the Levelogger to communicate with a
desktop or laptop PC, or a Leveloader Gold.
The Direct Read Cable system is composed of the ordered length of Direct
Read Cable, the Direct Read Wellhead and the PC Interface Cable. The Direct
Read cable threads to the Levelogger, while the socket at the opposite end of
the Direct Read Cable fits into the specially designed Direct Read Wellhead. The
PC Interface Cable connects to the Direct Read socket at surface and to either a
USB or RS232 port on the PC (Fig.11-5). While use of the Direct Read Wellhead
is recommended and convenient, it is optional as long as a satisfactorily secure
alternative tie-off point is found for the Direct Read Cable. Follow these steps to
install a Direct Read Cable Assembly to the Levelogger:
1. Remove the installation cap from the Levelogger, align and connect the
optical socket (two glass ‘eyes’ using the alignment pin) of the Direct Read
cable to the Levelogger by threading the coupling onto the Levelogger tightly.
2. The Levelogger and optical socket will fit through the hole in the Direct Read
wellhead. Use the eyelet at the bottom of the wellhead to securely tie-off
the cable and logger. Do not suspend the logger and cable from the surface
socket.
3. Remove the protective cap from the non-optical socket at the wellhead end
of the Direct Read cable, seat the socket in the Direct Read Wellhead and
align and thread it to the round socket of the PC Interface Cable.
4. Connect the USB or RS232 socket of the PC Interface Cable to the USB or
RS232 Com Port on your PC.
5. The plugged hole in the wellhead can be removed to provide an access port
for a water level meter probe.
When removing a Direct Read Cable from a Levelogger, ensure you only
twist the coupling. To avoid possible damage, do not twist the strain relief
on the Direct Read Cable.
