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 forwater and chemical liquids.
• The most suitable for flow totalizing of extreme low flow regions ! Many deliveries for fuel measurement ofburners 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 certaincapacity is discharged. Therefore, we can measure the volume of theliquid by measuring the number of rotation of the oval gear.

As a flow meter for the filling apparatus ofvarious liquid…
Using valves and pumps, injections of various liquids are common inalmost all of industries. FLOWMATE has been successfully used forapparatuses that need the correct filling amount. The aluminum type
is used for oils and stainless type is used for water and chemicalliquid. In addition, as FLOWMATE covers a broad flow range with thesize from size 38 to 45, they are being used in variety of industries.

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

As a flow meter to control a combustion
equipment…
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 offuel flow rate of a small fuel system and centralized controlsystems.

As a standard flow meter for the testing of flowof a small pump…
Conventionally burette has been used in the flow test of small pumps.
By adopting FLOWMATE with output signal function as the standard
for an automatic setting device of discharge flow, more reliableinspection and flow rate setting method are achieved. As small pumps
are intended to inspect many units simultaneously, a flow meter tosave space and is reliable, but inexpensive model is required.

As a flow meter to control the combustionof a burner…
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 aburner, size 39 (flow range: 1 to 15L/h) of robust aluminum body isavailable.

As a flow meter to fill various liquid forcompleted cars…
At final process of car factory, various liquids such as engine oil,washer fluid, break oil and gasoline need to be filled into a completedcar. With its compactness and high reliability as advantages,
FLOWMATE makes a precise filling process, enabling to record eachfilling 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.

As dust powder preventive method in thecase of cutting out semiconductor chips…
Dust powder
preventive

There is a process to apply dust powder preventive to curb the dust
caused by cutting out semiconductor chips.
FLOWMATE is widely used to adjust and control the applied flow
rate, because of its excellent repeatability in flow rate measurement.

Cutout ofsemiconductor chips

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 andmakes stable production by taking advantage of its extremely low
flow rate.
