For cooling water in engine room

EF-AUTOElectromagnetic Flowmeter

OUTLINEThe electric connection part of detector has been miniaturized, so thatthe electromagnetic flowmeter, suitable for the flow measurement ofcooling water in the engine room of automobile, may be able to beeasily installed in the engine room, and also radiator hose has been
made to be connected directly.

FEATURES❏ The hose fitting is detachable, and it can be made according to thediameter of required hose fitting, and the measurement for different
hoses in inside diameter is easily made just by exchanging the fitting.
❏ The reduced tube has been adopted because of no projection atflow path, very small pressure loss, and no influence by the piping,up- and downstream.
❏ The part of electric connection of detector has been made smaller,
using the exclusive cable with connector, and it is possible to makewiring by one-touch.
