2.1 Flowmeter system overview
•
The Thermo Scientific Sarasota 2000 is an ultrasonic multi-path flowmeter, which
complies with ISO6416.
•
It employs state of the art technology to achieve excellent performance in conditions
which have previously been outside the scope of this type of instrument.
•
Smart transducer technology incorporating drive and receiver circuits optimises signal to
noise ratio and minimises losses. The smart circuits are located inside the transducer
housings except for the 1 MHz transducers. In that case they are in sealed in-line
housings known as Tboxes.
•
Automatic adjustment of receiver gain and transducer drive voltage (HT).
•
Low power consumption and intermittent modes make mains free operation feasible.
•
Multi-path operation, (up to 32 via multi-drop facility made possible by smart transducer
addressing.)
•
Multiple depth inputs,
-
up to 16 ultrasonic depth transducers
- up to 4 auxiliary depth gauges (via 4-20 mA inputs.)
- up to 2 auxiliary depth gauges via BCD inputs
- up to 2 depth inputs via pulses direct from direct from shaft encoder.
•
Multiple flow channels – up to 4 separate channels measured by a single instrument. The
velocity paths and depths are allocated to the channels during set up.
•
Up to 4 analogue 4-20 mA outputs and two 16 bit binary coded decimal (BCD) I/Os
•
Overall system alarm relay
•
Four relays (volt free contact) option. Programmable, for example for alarms, status,
totaliser pulses.
•
Three serial ports. RS232 for PC, RS232 for modem and RS485 for site multi-drop
instrument communications
•
IR communication link alternative for PC
•
Internal data logger, 1 Mbyte capacity, programmable.
•
Water temperature measurement at each smart transducer (except 1 MHz transducers)
