Sibata LV-20N Operation Manual

1. Overview

The LV-20N/LV-30N is a float type (area type) suction pump flow meter. The suction flowrate can be
adjusted using the needle valve provided with the instrument. A pressure gauge is also provided,
which allows the suction pressure to be measured. This is ideal for measuring and adjusting the
flowrate of suction pumps.
