L'explication/l'anotation:For determination of liquid level in Bakus and ranging to ïîâåð
õíîñòåé with high reflection of ultrasound.
La description détaillée de marque:Transceiver, the shaping facilities
ultrasonic parcels and admission of echo signal consists of, processing microcontroller
echo signals.
the device may to work in one of the following the conditions:
a) calibrating of measurement channel using
ðåïåðà-îòðàæàòåëÿ, established in fixed, beforehand well-known
distance from radiator, that allows to define the speed
ultrasound spread of measurement conditions;
b) the calculation of propagation velocity of ultrasound using
probe of medium temperature. the probe may be positioned at housed
ultrasonic measurer or was taken out at some point of Baku.
at the output of measurer it is able to obtain:
1) running value of liquid level in Baku;
2) parcel of liquid in Baku;
3) fluid mass in Baku;
4) steams temperature above liquid level.
the measurer has following the communication interfaces:
- còàíäàðòíûé interface of RS-232 with connection capability to PC
- interface of RS-485 with connection capability to PC
- serial interface current loop 4-20 mitotic activity.
