Be able to check the color of the fluid or an intermittent flow.The use of a mica plate makes this type of sight glass available for steam condensate.
For visually checking the variation in the flow rate of the fluid.
The rough flow rate can be identified from the position of the flap. For large flow rates.
It is possible to enter the scale as requested. The indication accuracy is about ± 10% of full scale.
The variation in the flow rate can be identified from the movement of the ball. For small to medium flow rates.
The variation in the flow rate can be identified from the rotation of the spinner. For very small flow rates.
Changes in flow rate can be confirmed by the rotation of the impeller.
Use to protect from glass scattering.
It can clean the glass from inside by wiper.
Use to protect from damage.

What is flow meter?
A device that measures the volume of fluid that passes through a section such as pipe line per unit time. The flow rate per unit is called the instaneous flow rate, and the flow rate that passes within a certain period of time is called the integrated flow rate.
Kinds and usage of flow meter
When a flapper is placed in the fluid, the plate receives a force proportional to the square of the flow velocity. The instantaneous flow rate is measured by balancing this force with elasticity of the spring. Because of its robustness, it exhibit stable performance even in harsh usage environments, and is used in wide range of industrial fields such as steel rolling lines and cooling devices.
A throttling mechanism is provided in the pipe, and the differetial pressure generated before and after it is measured according to the magnitude of the flow rate to determine the instantaneous flow rate. It has a simple structure and can be applied to liquids, gases, vapors, and is used in a wide range of fields as a factory flow meter.
It consist of a constant volume measuring chamber and a movable part that is automatically driven by the pressure of fluid. Each time, a constant volume of fluid passes through the flow chamber, the movable part is driven once and the number of times the movable parts is driven find the integrated flow rate or instantaneous flow rate. Because it is a measurement formula that directly measures the flow rate, it has very high accuracy and is widely used for petroleum trading.
When a float is placed in a vertical taper pipe and fluid is flowed from below the taper pipe, the float stops at a position where the fluid force applied to the float balances with the apparent mass of the float. The instantaneous flow rate is measured from the rest position of this float. It is used as a management flow meter at the low cost centering on the field indication type.

1. It can monitor the flow rate and see the index even the application is black oil. Changing of the amount of oil can be seen clearly since the index is indicated outside of wetted parts.
2. Rough flow mesurement is available (option). More accurate refueling management is available due to adopting 3 to 4 points on scale description.
3. It is available to monitor the oil adjustment and inspection of high place with back pressure and the place where difficult to close. This type can arrange from B-MFI-1(1 body) to B-MFI-10(10 bodies) so if there are many refueling points, it is convenient to install at 1 place.

Water-proof type
The SF type series is used in a wide range of fields such as lines that require flow monitoring, such as cooling lines, lubrication lines and various plants, because the scales are large and the flow rate indication value are easy to read.Product specifications can be adjusted according to the type of oil used.
Features<SF-M type flow meter>
The instantaneous flow meter displays the flow trate per unit time. Please specify the unit. · Special Specification products are compatible with high temperature and high pressure fluids.(Up to 21MPa, up to 300°C)
· The waterproof type can be used outdoors and in poor atmosphere condition. · Please select the model SF-M-V(earthquake -resistant) for locations with lots of vibration.
<SF-MA series, SF-MAA series flow switch>1 point (MA type) or 2 points (MAA type) can be added to the flow meter as an alarm output. When the contact reach to the specified flow rate, the reed switch is activated and the switch function is activated. In addition to the features of the SF-M type flow meter, it has the following features. · Contact operation is reliable. · The contact flow rate can be set arbitrarily (within the case) within the scale range. Please specify the external variable type when it is frequently variable.
· Large contact capacity · Intrinsically safe explosion-proof types are also available. (Safety cage is included upon request). · Please specify the earthquake-resistant SF-MA-V type or SF-MAA-V type for locations with a lot of vibration. However, the contact is reed switch.

When using
The SF type flow meter is a magnetic coupling type. If iron powder is expected to be mixed in the measured
fluid, remove it with a strainer. It may cause malfuncton.
Use in a direction other than the flow direction specified when ordering may cause a flow rate error. Do not
use it in a direction other than the specified flow direction.

When using
The SA type flow meter is a magnetic coupling type. If iron powder is expected to be mixed in the measured
fluid, remove it with a strainer. It may cause malfuncton.
Use in a direction other than the flow direction specified when ordering may cause a flow rate error. Do not
use it in a direction other than the specified flow direction.

Oil, liquidCold and hot water Steam
Micro flow rate Medium flow rate Large flow rateSmall flow rate
The RF type series is a compact and highly accurate flow meter that can measure water and oil as well as chemicals. The number of rotations of the two trilobe elliptical gears gives a signal that is directly proportional to the flow rate.In response to this signal, the instantaneous flow rate or integrated flow rate is displayed on the indicator.
Features
<RF- type electric transmission type >Various outputs are possible by using a converter (contact point signal output from the RF-Ⅰ type according to the application.
<For RFH type high pressure & high viscosity fluid > Accurate lubrication amount can be grasped and proper lubrication can be performed. Since it can be used for oil pressure 21MPa line, there is no restriction on the installation location on the
piping line. It can used to any grease of all consistency. Consistency 85-475, No.006~6 Instantaneous flow and integrated flow can be switched with a single touch, and the integrated display
can be reset. The indicator has dust proof/drip-proof structure. Various outputs are possible by using a pulse signal converter for the application. In that case, select from RF- type telemetry system No restrictions on flow direction. Up Down, Right Left, measurement is possible in any direction.

The INF type series is a compact flow meter that can measure the flow rate of liquid and gas with horizontal
piping while being an area type flow meter.
Features
<INF-M type> Since it is shuttle type, it can be used for horizontal piping. An area type flow meter with a metal taper pipe has a flow direction for horizontal piping. High accuracy and wide scale range is possible.Accuracy, FS x within ±2%.Scale range, FS x 1/10 to FS (Example: 1L/min to 10L/min) Measurement of any fluid is possible. Liquid and gases can be measured, and products with excellent corrosion resistance can be manufactured by selecting the main body and the components required. Suitable for high temperature and high pressure fluids. Standard products have a heat resistance of 80 degrees, but can manufacture up to 300 degrees with special specifications. The standard pressure is 1.5MPa, but it can be manufactured up to 30MPa with special specification.
<INF-MA type > Contact operation is reliable. Since the micro switch is turned on and off with circular cam attached to the external magnet shaft, there is no miss shot. The contact is variable at full scale, and the contact operating point is indicated on the scale by the setting needle. Since the contact configuration is a micro switch, a differential is generated during ON/OFF operation of the setting. This differential value varies depending on the set flow rate and piping diameter. Please contact us each time. Large contact capacity Since the micro switch is used for the contact, the contact capacity is larger than that of a reed switch, and an auxiliary relay is not required. Use a waterproof type outdoors or in a poor atmosphere.
The waterproof structure of this device is JIS C 0920immersion type. (IEC IP67).
