Endress+Hauser Prosonic FMU 862 User Manual

Technical
Information
TI 190F/00/en
Applications
Prosonic FMU 860...862 ultrasonic
transmitters are for use with the
Prosonic FDU 80...86 family of sensors.
The transmitter determines levels in
silos and tanks and calculates the
volume of solids and liquids they
contain.
With the appropriate certified sensor,
measurements can be made in
explosion hazardous areas, zone 1 or in
combustible dusts.
When used for applications in fresh and
waste-water, Prosonic measures
•
flow rates in flumes and weirs
•
water levels
and can control screen cleaning and
pumps.
Features and Benefits
A customised instrument programme for
the specific application.
Choice of transmitters
•
For the field or control room
•
Single or two-channel versions with
three or five relays, also with optional
totaliser
•
With optional serial interface for
remote configuration (INTENSOR or
HART protocol)
•
With RS-485 interface
Intelligent commissioning, ultrasonic
measurement par excellence
•
Instrument parameters arranged in a
simple matrix
•
Various linearisation functions,
totalisers, and all common Q/h curves
on call
•
Quick commissioning and stable
measurement thanks to signal pattern
recognition by fuzzy logic and the
application parameter
