GSM-GPRS module dedicated to use on tanker-truck
application.
Module is intended for
remote monitoring fuel level in compartments of fuel
trailer (semi-trailer), remote supervision of
tanker-truck movement, monitoring of tractor (track)
fuel consumption and tanker-truck status.
Module has two digital
communication interface EIA-485.
Module supports up to THREE regular fuel tanks and up to
ELEVEN cargo tanks (cargo compartments). |
