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.

When using

Since FY type series flowmeters are of magnetic coupling type, if it is expected

that iron powder will be mixed into the measured fluid, remove them with a

strainer. It may cause malfunction.

Use in direction other than the direction specified when ordering will cause flow

rate errors. Do not use in directions other than the specified direction.

KY series flow indicator

The KY series is a product developed for lubrication equipment and is ideal for low-cost and hard specification environments

Features

<KY-M type flow meter >The instantaneous flow meter displays the flow rate per unit time. Please specify the unit. Fast reaction speed due to direct acting type. Due to the structure that does not use magnets in the fluid, it is hardly

affected by iron powder. KY type is more compact compare to SF type.

<KY-MA type flow switch >1 point can be added to the flow meter as an alarm unit. When the specified flow rate is reached, the micro switch is activated and the switch function is activated. In addition to the features of the KY-M type flow meter, it has the following features. Contact operation is reliable. Contact capacity is large. The contact flow rate can be set arbitrarily (in the case) within the scale range. Please specify the external variable type when it is frequently variable. Intrinsically safe explosion-proof types are also available. (Safety cage is included upon request).

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).
