3 Types an Main s of es Sight glasses are use as components for visually checking the flow of the flui insie piping from outsie. Plain type For checking whether a flui is present or how two fluis are mixe. Be able to check the color of the flui or an intermittent flow. The use of a mica plate makes this type of sight glass available for steam conensate. Flap type The rough flow rate can be ientifie from the position of the flap. For large flow rates. Ball type For visually checking the variation in the flow rate of the flui. The variation in the flow rate can be ientifie from the movement of the ball. For small to meium flow rates. Spinner type The variation in the flow rate can be ientifie from the rotation of the spinner. For very small flow rates.

The flow rate shown by the scale on the scale plate for a flap type sight glass is just for reference. It is not available as a flowmeter. Sight glasses can be installe in any posture.

5 ater Plain type Ductile iron S-1S1F 1. Mixe state or color of two component flui can be checke. 2. Intermittent flui flow can be checke. 3. Can be connecte to horizontal/vertical piping. 4.

7 ater Ball type Ductile iron SB-1S1F 1. Flowing state of flui can be checke with the movement of the balls insie the sight glass. 2. Insie glass surface is less liable to water scale since the balls roll an contact the surface. 3. Compact, lightweight an space saving. 4. Can be connecte to horizontal/vertical piping (but glass part shoul face sieways). Moel Boy Material Glass Ball Glass part an balls are consumable supply.

9 ater Flap type Ductile iron 1F 1. Variation in flow rate can be checke easily with flap an scale plates. 2. Pressure loss cause by the flui flow is as low as 0.01 MPa even when the flap shows the maximum flow rate, an oes not affect the pressure of the flui. 3. Can be connecte to horizontal/vertical piping. 4. Mica plate is use for this type of sight glass for steam conensate. 5.

10 Spinner type Bronze ater No nee for cleaning of the ome since rotating spinner keeps the insie of the ome clean. 2. Flui flow can be etecte from the rotation of the spinner, an flow rate change is ientifie by its rotating spee. 3. Easy to assemble an isassemble ue to simple esign. Can be connecte to horizontal/vertical piping.
