Model 40 FLOWMATE
• High reliability! Highly reliable oval gear flowmeter of excellent accuracy, repeatability and responsiveness.
• Selectable materials! Inexpensive aluminum body for oils, and highly durable stainless steel types for
water and chemical liquids.
• The most suitable for flow totalizing of extreme low flow regions ! Many deliveries for fuel measurement of
burners and heaters.
• Simple structure, robust and inexpensive! Easy-to-fasten metal connection of high durability.
• Most suitable for installation on equipment! Easy to handle, small and regular square shape.
• Can be combined with pumps and valves! Many deliveries for proportional injection of chemicals
and foods, and flow control.
• Can accommodate to designated specifications by customer! In response to the installation condition,
the specification can be altered.

Principle of Operation When the liquid flows, a pair of oval gears rotates, measuring a certain
capacity (the part of crescent).
When the oval gear rotates one time, the liquid of 4 times of a certain
capacity is discharged. Therefore, we can measure the volume of the
liquid by measuring the number of rotation of the oval gear.

As a flow meter for the filling apparatus of
various liquid…
Using valves and pumps, injections of various liquids are common in
almost all of industries. FLOWMATE has been successfully used for
apparatuses that need the correct filling amount. The aluminum type
is used for oils and stainless type is used for water and chemical Valve

liquid. In addition, as FLOWMATE covers a broad flow range with the Pump Flow meter

size from size 38 to 45, they are being used in variety of industries.

As a flow meter to measure fuel efficiency Return side

mounted on cars…
FLOWMATE can be mounted in the engine room of a car to measure
Fuel tank
the fuel efficiency because of its high accuracy, easy to handle Engine
compact design, and tolerance to the vibration of a moving car as
main reasons. The meter can be used for gasoline, as well as to Supply side
Fuel indicator
measure supply and return flows of diesel engines.

As a flow meter to control a combustion

equipment… Steam

FLOWMATE is a small, inexpensive and unique made in Japan

flowmeter, being widely used in the world to control oil flows for
combustion equipment and energy saving.
The meter can be used to monitor a small boiler, the indication of
fuel flow rate of a small fuel system and centralized control Kerosene
systems.
Water

As a standard flow meter for the testing of flow Burette

of a small pump… (a glass tube)

Conventionally burette has been used in the flow test of small pumps.
Flow rate
By adopting FLOWMATE with output signal function as the standard setting machine Comparison to
for an automatic setting device of discharge flow, more reliable Photoelectric
the burette
sensor
inspection and flow rate setting method are achieved. As small pumps
are intended to inspect many units simultaneously, a flow meter to
save space and is reliable, but inexpensive model is required.

As a flow meter to control the combustion

of a burner…
Controller
Grain
Flow meter manages fuel efficiency of a burner in a grain drier. As
FLOWMATE has five sizes, enabling themselves to match with proper
flow range of each customer. As a specialized FLOWMATE for a
burner, size 39 (flow range: 1 to 15L/h) of robust aluminum body is
available.

As a flow meter to fill various liquid for To improve reliability

with a comparison of two
completed cars… indicated values.

At final process of car factory, various liquids such as engine oil,

washer fluid, break oil and gasoline need to be filled into a completed
car. With its compactness and high reliability as advantages,
FLOWMATE makes a precise filling process, enabling to record each
filling and change of the filling amount with a one-touch operation.
A mount type for quick installation and disinstallation for examination
and replacement is available. Size 45 and bigger are also available.
Mount type
As dust powder preventive method in the
case of cutting out semiconductor chips…
There is a process to apply dust powder preventive to curb the dust Dust powder
preventive Cutout of
caused by cutting out semiconductor chips. semiconductor chips
FLOWMATE is widely used to adjust and control the applied flow by a blade or a laser
rate, because of its excellent repeatability in flow rate measurement.

As a flow meter to control the applied

quantity in metal processing…
In precise processing of aluminum, there is a process predetermined
curve has to be made, by applying extremely small amount of oils.
FLOWMATE is incorporated into the processing machine and
makes stable production by taking advantage of its extremely low
flow rate.

As an inexpensive explosionproof Non-hazardous area Hazardous area

flow meter… Control panel
FLOWMATE
By using the explosionproof sensor, FLOWMATE can be used in
hazardous area. It can be used as an inexpensive explosionproof Coating
apparatus,
flow meter 1 in a painting booth. etc.
