2.1 Flowmeter system overview
•
The Thermo Scientific Sarasota 200 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 4) with multi-drop facility made possible by smart transducer
addressing to save cable.
•
Multiple water level inputs, subject to a maximum of 4 overall:
-
up to 4 ultrasonic level transducers
- up to 2 auxiliary level gauges (via 4-20 mA inputs.)
•
Up to 2 analogue 4-20 mA outputs
•
System fault relay (volt free contacts)
•
2 programmable relays, 1 volt free contact, 1 high speed solid state. Programmable, for
example for alarms, status, totaliser pulses.
•
Two serial ports. RS232 for PC, RS232 for modem.
•
Internal data logger, 1 Mbyte capacity, programmable.
•
Water temperature measurement at each smart transducer (except 1 MHz transducers)
