Telelin make double window side flow indicators are used for visual indication of flow in vertical as well as horizontal pipelines. It enables maintaining flow of the liquid by viewing instantaneous flow and guides for any subsequent change in flow desired. Various different models are available as per required application and in different material of construction, M.S, 304 S.S, 316 S.S.
- Model : 200S-FLT - (Flapper Type)
200S-FLT sight flow indicators are recommended for both horizontal and vertical pipe lines with upward flow although frequently used for gases. Flapper type is best suitable to transparent or slightly opaque liquids. Position of flapper indicates variation in flow rates may be supplied without flapper where no internal indicator is required.
- Model : 200S-DRT - (Drip Type)
200S-FDT sight flow indicators are best adapted to vertical downward flow designed without any obstruction this type is particularly useful in distillation and similar apparatus where flow is apt to be intermittent.
- Model : 200S-ROT - (Rotary Type)
200S-ROT sight flow indicators operates successfully in any position but are particularly adapted to pipelines carrying dark solutions where the motion of the rotor is easily detected. they are equally adapted to transparent solutions and gases and are frequently installed where observation is to be made from distance. Available with rotor of PVC, PP, PTFE or metal.
- Model : 200S-PT - (Plain Type)
200S-PT sight flow indicators are plain without any internal indicator and services as observing window and are suitable for vertical as well as horizontal lines and are adapted to liquids and gases.
- Model : 200S-FLT- (Flange Type)
200S-FLT sight flow indicators are plain without any internal indicator and services as observing window and are suitable for vertical as well as horizontal lines and are adapted to liquids and gases. Flange ends enables easy mounting in the line with proper lick proof gaskets. Spare matting flanges and nut-bolts (hardware) can be provided at extra cost.
