3.3 - Meter orientation
For proper use, install the TECH-FLOW, MAT-FLOW or R-FLOW meter as
instructed on the back (fluid direction arrow).
The meters can have fluid outlet upwards, downwards, to the left or to the right.
4 - GENERAL INDICATIONS
4.1 - General Information
TECH-FLOW, MAT-FLOW, R-FLOW meters have 1” BSP-G threaded inlets and outlets that are flanged
on both sides. The meter is designed for fixed installation on a line.
IMPORTANT:
Do not use conical connections that can damage the meter. When installing position a suction filter of at least 40 mesh
.
4.2 - Mechanical meters
TECH-FLOW, MAT-FLOW, R-FLOW mechanical meters can have a 3-digit or 4-digit numerator, depending on
the version chosen. The meter is delivered pre-calibrated by the manufacturer and ready for installation.
IMPORTANT:
Due to the different operating conditions, pre-calibration may be different than the
one required; it is therefore recommended to calibrate the meter with each installation (see CHAP. 5).
5 - CALIBRATION
5.1 - Fluid
Fluid litres = Fluid weighed ÷ Fluid density
Flow rate (in litres per minute, LPM) = Fluid litres ÷ Fluid dispensing time (in seconds) · 60
