4 – Instruction Manual – Atrato Ultrasonic Flowmeter Setup

Ultrasonic Flowmeter Setup

Before use, download and install Atrato software from memory stick or website. The Atrato low-flow ultrasonic flowmeter should be setup using the USB interface and a suitable computer. Below is a screen shot of the Configuration screen.

Ultrasonic Flowmeter Setup

The 3 tabs at the top of the display are, “Configuration, “Real Time-View” and “Advanced”.
The panel below shows the functions of the panel on the top left of the screen.

Atrato Ultrasonic Flowmeter Setup – Display

DISPLAY MODE:

The down arrow selects from the
various display and Atrato functions.

Rate – The display will show flow rate only.
Total – The display will show total flow only.
Both – The display can be cycled from rate to total
using the left hand button on the Atrato or
the left button in the “Real time window”. A
remote input can be used if either pin 6 or
pin 7 has been utilised.
Batch – This is a separate function and several
selection parameters change once this is
chosen. See batching option on page 15.


Right push buton resets total :
ultrasonic flow meter reset

Check this box if you require the total resettable by either the right push button or remotely through pin 6 or 7.
Selectable only in “Total” or “Both” modes


Units: 

ultrasonic flow meter units

A drop down menu offers the choice of – Litres, cc, gms, kg, US gallon, Imperial gallon or Custom units.
Selecting Custom Units leaves the Units area blank.

RATE (units per):

ultrasonic flow meter - rate

This is the time base for the flow rate and has the option of Second, Minute or Hour.


RATE DP POSITION:

ultrasonic flow meter Rate DP positions

Use the drop down menu to choose the required decimal point position.


TOTAL DP POSITION:

Use the drop down menu to choose the required decimal point position.


Decrease total for –ve flow:

The meter will not register negative flow unless this box is checked.
For reverse flow the rate will show a “-“ sign before the rate and the total will be reduced accordingly.

One of the transistor outputs (PNP or NPN on Pin 6 or Pin 7) could be
configured to give a logic level when reverse flow is detected.


Atato Ultrasonic Flowmeter SCALE

Scale factor adjustment:

This is a fine tune adjustment on the signal to compensate for errors introduced by erratic flow or other system irregularities.

Density:

The flowmeter is fundamentally a volumetric device but a density
figure can be entered here if one of the mass units are selected.
Caution must be used however as there is no temperature/density correction.
