Choose a sub category:

Dakota Instruments' Encased Glass Flow Meters exemplify traditional variable area precision glass technology of classical rotameters. Rib-guided or fluted glass flow tubes are available for low, medium, and high flow capacities. Shipped completely assembled, rugged frames are 316 stainless steel, brass, aluminum, or PFA coated. A thick protective front shield and back plate, and optional built-in control valve for most models allow a wide range of applications. Units are particularly suitable for indicating and controlling gases in manufacturing processes, metering carrier gases, and liquid and gas measurement in level indicating, laboratories, and pilot plants.

Economical encased glass tube rotameters for reliable low, medium, and high flow capacities
Rib-guided or fluted glass tubes facilitate stable, accurate readings
OPTIGRAD™ scales minimize parallax and eye fatigue
Magnifier lens in front shield enhances reading resolution
Rigid construction
Optional built-in Utility or high resolution Precision needle valve

Encased Glass Tube In-Line Flow Meter with Valve, Brass 3/8" FNPT Adapter

Incorporating traditional variable area precision glass technology, these rugged brass in-line flow meters offer accurate and economical solutions to medium flow range measurements. These meters are designed with unique rotatable scales of dual air-water direct reading graduations showing SCFM and SLPM (air), as well as GPM and LPM (water) markings. Valve included.
150mm PTFE Encased Glass Tube Flow Meter with CV Utility Valve, 1/8" FNPT Adapter

These rugged 150mm PTFE-Glass Flow Meters offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids and gases. Wetted inert components are surrounded by structurally rigid anodized aluminum. The resultant design represents a unique combination of a rugged mechanically rigid frame and chemically inert wetted parts. This rotameter comes with a CV Utility Valve Cartridge. CV® Valve Cartridges are designed for adjusting flow rates in applications where high resolution metering regulation is not essential.
65mm Aluminum Flow Meter with High Precision Valve (MFV)

Designed for low flow rates, these 65mm Single Tube Aluminum Flow Meters are precision instruments embodying the inherent simplicity, versatility and economy of the classical variable area meter. They are particularly suitable for metering carrier gases in chromatography, in manufacturing processes, liquid and gas measurements in laboratories, pilot plants, flow and level indicating and controlling gases. This rotameter comes with a High Precision MFV Metering Valve. MFV Valves are ideal for adjusting flow rates whenever high sensitivity control and resolution are desirable, particularly in conjunction with metering tubes of very low flow rates.
