To set up the level meter and collect the measured data, it is necessary to have a HART®
communicator, which can be used to communicate directly with the level meter or use it to
mediate communication with a peripheral device, see Fig. 18.
For this purpose, Dinel
®
offers the UHC-01 converter, which is designed for connection of all
level meters supporting the HART
®
communication protocol over the current loop in order
to configure them and read the measured values via the appropriate software on a PC. The
supplied software from Dinel s.r.o can be used as software. or possibly another that can
communicate via the HART
®
protocol via a virtual serial port.
The UHC-01 converter allows you to switch the communication HART
®
resistor (250 Ω) on or
off using a mechanical switch.
In addition to the input and output for HART
®
communication, the UHC-01 transmitter also
contains a power supply for measuring probes (24 V / 45 mA) with short-circuit protection.

•
START OF RANGE
The actual minimum possible value of the primary quantity measured. It can be changed
in the menu [link to menu 9.6.2] in the range given by the LOWER LIMIT and UPPER
LIMIT values.
•
DAMPING
An averaging value that allows you to suppress unwanted fluctuations at fast and jump
changes in the measured quantity. It can be changed in menu [link to menu 9.6.4]
•
SERIAL NUMBER
Device serial number.
