FLUID CONTENTS MAY BE HAZARDOUS
The meter must be fully depressurized and drained before attempting to remove the transducer
housing. If fluid begins to leak from the transducer housing, immediately reinstall it.
Failure to do so may cause serious injury or equipment damage.
ESCAPING FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Daniel components/seals and materials
compatible with the chemical properties of the measurement fluid.
Failure to select suitable meter components/seals may cause escaping fluids, resulting in injury or equipment
damage.
