DISPLAY

3.5 BACKLIGHT

(BRIGHTNESS)

The unit has a backlight. The backlight brightness can be adjusted from off
(0%) to max (100%) in steps of 20%.

●

The brightness cannot be adjusted for battery powered units.

●

When the unit is only loop powered, it cannot use the backlight. An
external supply is required instead.

3.6 BARGRAPH

The unit has a speedometer/bar graph around the edge of the display that
gives a quick impression of the actual flowrate. The following can be
selected:

●

Enable

: the bar graph is switched on.

●

Disable

: the bar graph is switched off.

3.7 RATESPAN

Sets the range of the speedometer. The display shows 0 – 100 and has 20
blocks. Therefore, each block represents 5% of the total range.

The number of decimals displayed depends on 

2.3: FLOWRATE > DECIMALS

.

 MENU 4: FLOWMETER

To simplify the configuration of the Flowmeter, Total and Flowrate settings, the E126-P-EL has an
automatic unit conversion feature. To use this feature, you only have to enter the average K-factor
and the related measurement unit.

Advantages/features

:

● The same K‑factor calculation is used for Total and Flowrate.
● All configuration is done in the Flowmeter menu.

The measurement units can be set for volume or mass units. Refer to the test/calibration certificate
provided with your flowmeter. The automatic unit conversion feature can be set to ‘Hand’, allowing
for independent configuration of total and flowrate, for example, when:

● measurement units are not supported, i.e. ‘revolutions’, or
● volume and mass units are used simultaneously.

Use the following procedure to set up the automatic unit conversion:

1.

4.1: FLOWMETER > SIGNAL

: Select the correct type of flowmeter signal.

2.

4.2: FLOWMETER > UNITS

:

 Select the type of measurement unit (volume or mass) shown on the

certificate.

3.

4.3: FLOWMETER > UNIT

:

 Select the measuring unit shown on the certificate.

4.

4.4: FLOWMETER > K-FACTOR

:

 Enter the (average) K-factor shown on the certificate.

5.

1.1: TOTAL > UNIT

:

 Select the desired measuring units for (accumulated) Total.

6.

2.1: FLOWRATE > UNIT

:

 Select the desired measuring units for Flowrate.

For a detailed description and tutorials on the automatic unit conversion feature, refer to our website
(or ask your supplier).

Example

: How to manually calculate the K-factor for total or flowrate:

● The Flowmeter generates 65.231 pulses per US gallon.
● The required measurement unit is cubic feet (ft

3

).

● A cubic foot = 7.48052 gallons.

Formula

Pulse per US gallon x cubic foot (in gallons) = 

K-factor

65.231 x 7.48052 = 

487.9618

For this example, enter 

487.9618

 as the K-factor for total or flowrate.
