2.1 Functions
This chapter summarizes the functions of the ultrasonic flowmeter. Please refer to Chapter 2.2
“Operation” for setting methods.
2.1.1 Flow display
Flow values are composed of numerical units.
Normally volumetric flow is the unit of measurement used, but measurement can be converted to
mass flow if liquid density is set manually or default value. Besides specific heat coefficient will be
requires for heatmeter.

(1) Numerical section
The numerical portion of the display consists of a maximum 7 digits sequence, excluding
alphanumeric but including decimal point although forward flow display consists of numbers and
decimal point only, no symbols. (However the maximum measurable flow value is 999999.)
Flow display digits and decimal point position is determined by system setting as below.
If exceeded digits, “-----------” will be displayed.
