Hardware
The QS3600 flow monitor is housed inside a cylindrical aluminum canister that is 62
cm (24 in.) long and 17 cm (6.6 in.) in diameter. The canister lid contains ultrasonic,
pressure, velocity sensor, and communication cable connections as well as rain gauge
and sampler communication cable connections. With the lid in place, the canister is
airtight and waterproof.
Warning : Only ADS Service Technicians are authorized to perform
component level service on the QS3600. If the monitor’s housing is opened by
unauthorized personnel, its IS certification is compromised.
A one-piece chassis attaches to the inside of the monitor lid to provide a mounting
surface for the central processing board (CPU board), the depth interface (for the
ultrasonic level sensor and the pressure depth sensor boards), the velocity interface
(for the Doppler velocity sensor board), and the power supply board (with the internal
modem).
