rotameter

[rō′tam·əd·ər]
(engineering)
A variable-area, constant-head, rate-of-flow volume meter in which the fluid flows upward through a tapered tube, lifting a shaped weight to a position where upward fluid force just balances its weight.

Too much pulsation in the flow stream will show up as apparent vibration, or bouncing, of the rotameter's float, and this is an indication that the observed flow cannot be relied on as accurate.
Addressing flow pulsation in medical device pumps: Diaphragm-type vacuum pumps are often ideally suited for a variety of medical devices. Unfortunately, flow pulsation can offer a challenge to developers, specifically in flow measurement and control. This article will focus on some simple techniques for reliable and repeatable measurement of flow and pressure, particularly where the pumped media is air or an otherwise compressible gas
KDG Instruments' Rotameter range comprises glass and metal tube products, in sizes from 63mm to 500mm tube lengths.
Variable Area Flow Meters
These versatile optical sensor switches can be used with the company's P, S and T rotameters. A kit is available for comparable flow meters.
Optical Sensor Switches monitor flow rates simply
Models 104 and 107 liquid Flo-Sensors precisely measure flow rates of fluids as low as 13 mL/minute, and are designed as an electronic alternative to ball-and-tube rotameters. Stainless steel construction guarantees compatibility with virtually any chemical, including many solvents and organic compounds, according to the company.
