WARNING!

WIRING THE TRANSMITTER WITH THE POWER ON MAY RESULT IN
INTERNAL DAMAGE OR LOSS OF MEMORY! PLEASE MAKE ALL
WIRING CONNECTIONS BEFORE SWITCHING ON THE POWER.

4.1 Description

The Smart Transmitter is supplied with all vortex flow meter. It is designed to
be locally mounted or wall mounted, remote from the meter, for easy user access.
The local keypad/display can be programmed to display various process variables:
instantaneous volumetric and mass flow rate, total flow, temperature*, pressure*
and density* in engineering units.

The flow rate can be displayed in 30 different volumetric and 25 mass flow engi-
neering units. Flow meter parameters and functions can be programmed remote-
ly via the RS-232/RS-485 interface or locally via LCD/KeyPad using multi level
menus. Vortex flow meters support various functions including: two programma-
ble flow Totalizers, low, high or range flow, temperature* and pressure* Alarms,
two digital programmable optically isolated outputs, two programmable (for dif-
ferent process variables: volumetric flow, mass flow, temperature*, pressure*) 4-
20 mA analog outputs, programmable optically isolated flow rate Pulse output,
battery backed Real Time Clock [RTC], programmable process Variable Data Log

F) The meter can now be removed or inserted by putting a wrench on top of

the threaded shaft of the insertion tool and turning the shaft until the
meter is extracted from or inserted into the pipe.

G) After the meter has been extracted, the valve should be closed, and the

entire seal assembly unscrewed from the piping. The entire meter and
extraction tool is then removed from the pipe.

H) When reinstalling or removing the meter, repeat the entire procedure

starting with step A.

CAUTION: The shaft will not go completely through the seal assembly,
therefore, when the shaft stops extracting, do not apply additional
force or damage could occur.

ƽ

CAUTION: Remove the seal assembly slowly. There may be an
amount of pressurized fluid in the nipple, or the valve may not be
sealing properly.
