Product Details:

BrandTelelin
ApplicationIndustrial, Laboratory
AdvantagesClear glass is used which is highly resistant to thermal shock and chemical action

Other Details:

By Pass Type Rotameter are recommended for large flows in 2” & above size pipe lines, where direct on-line Rotameter is not possible for becoming very costly due to non availability of required dia. tube or large dia. tube respectively.


Assembly consists of:

A pair of 38mm thick orifice flanges with ½” BSP female pressure taping

A precisely bored & finished orifice plate

Necessary by-pass piping

2 Nos. Isolating valve

A rotameter in By- Pass line with range orifice plate.  By pass piping design (position) differs for vertical installation & horizontal Installation.


Details required for submitting offer:

Piping position / Flow direction i.e. Vertical: Upward / Downward. Horizontal : Left to right or right to left

Line size, exact I.D. & O.D. or Pipe schedule

Approx. Price: Rs 3,000 / NumberGet Latest Price

Product Details:

BrandTelelin
ApplicationIndustrial, Laboratory
Material AvailableMS, SS, PTFE, PVC etc

Other Details:
  • When fluid or gas flows through a taper tube containing a float, a pressure difference of p1 and p2 is created between upper and lower side of the float. the float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross sectional area of the float.
  • Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases.
  • Upward movement of float stops when the dead load is dynamically balanced by the differential pressure.
  • Tapering of metering tube is so designed that the vertical movement of the float becomes linearly proportional to the rate of flow and the scale is provided to read the position of the float, thus giving birth to flow rate indication.
