6 UFM 3030
Part A System Installation and Start-up
1 Introduction
1.1 Cautions
Only for flow meters supplied with a voltage over 50 VAC.
Refer all maintenance or service to trained KROHNE service engineers.
Mains power shall be disconnected from the product before performing any
maintenance.
This product is prepared for and can only function with the rated AC mains voltage
as indicated on the nameplate.
This product is a Class 1 device (earthed) and requires a correct connection to
protective earth. The protective earth conductor of the main power shall be properly
connected to the marked protective earth terminal to ensure safety from electric
shock for the operator and its environment. For detail refer to this service handbook.
1.2 Unpacking and inspection
•
This product has been thoroughly inspected and tested before shipment and is ready for
operation.
•
After carefully unpacking, inspect for shipping damage before attempting to operate. If any
indication of mechanical damage is found contact immediately the responsible transport service
and your local KROHNE representative.
•
A simple operating check of the electronics after unpacking and before permanent installation is
advisable to ascertain whether it has suffered damage during shipment. Confirm for the correct
mains voltage printed on the nameplate. If it differs from the ordered product please contact your
local KROHNE representative.
•
After connecting to the mains, check if there is any indication on the display and if the backlight
of the display is lighted. If not, contact your local KROHNE representative for advice.
1.3 System description
The UFM 3030 ultrasonic flow meter is a precision instrument designed for linear, bi/directional flow
measurement of liquids. Flow measurement values can be output via the standard analog and-or
pulse/frequency outputs. Via a user friendly operator interface (HMI) the unit can be set up for a
wide range of applications. Next to actual volumetric flow measurement the unit can be configured
to perform flow totalization (plus, minus and sum). Also measurement and output of the liquid sonic
velocity can be configured. Optionally the unit can be set to perform one of the following additional
functions:
•
Calculate and output corrected standard volumetric or mass flow using the external pressure
and temperature inputs
•
Batch function
•
Heat function, combining T1, T2 and volume
