RECEPTION
The flowmeter is supplied ready for installation and service.
The blocking elements that hold the float for transport should be removed before installation.
Turning the instrument up side down, check that the float moves freely in the tube.
INSTALLATION
The instrument must be installed taking into account the following:
The fluid inlet will be in the bottom of the flowmeter (the one nearest the scale's minimum value).
The fluid outlet will be in the top of the flowmeter (the one nearest the scale's maximum value).
It is very important that the position of the instrument is completely vertical, given that deviations of
about 5º– 10º can produce errors of about 10% of the reading.
Never open suddenly the regulating valve as this may cause the float to hit the glass tube
!
and break it.
FLOW RATE READING
The float determines the flow rate
measurement on the scale.
For the different shapes of floats, the
readings must be taken at the height
shown in the drawing at the right.
CLEANING AND MAINTENANCE
Remove the 4 screws (10) and the transparent protection (9) to gain access inside the body (1).
Screw up the measuring tube clamp (2) into the body head (1), until the metering tube (7) is free.
Remove the metering tube (7), taking care that the top and bottom springs (8 and 5) don't fall out.
Once the metering tube (7) is removed, withdraw the top and the bottom springs (8 and 5) and the
float (6). NOTE: The top spring is different from the bottom one and should not be interchanged.
Cleaning should be done using a soft brush (bottle brush or similar) to avoid scratching the
measuring tube.
The float should also be cleaned with a soft brush, never with metallic utensils which could scratch
it's surface
To reassemble the instrument, inspect the gaskets (4) to see if they are in good working condition,
and if not, change them.
Put the bottom spring (8) in the measuring tube (7), insert the float and the top spring (5).
Assemble the measuring tube inside de body.
Screw down the measuring tube clamp (2) from the body head (1), until the tube is tight and the
gaskets make a proper seal.
Put the transparent protection (9) in the body (1) and screw in the 4 screws (10).
