Product Overview

Aalborg Flow Meters
Designed for low flowrates, the Aalborg flowmeter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical variable area meter. Designed for specifically for corrosive ozone gas flow-rates, this flow-meter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical variable area meter. High precision needle valve ensures reliable and stable ozone flow adjustment.

Flow tubes for these meters are available with two types of scales, suitable for different types of applications

Direct reading scales are indicating flow rates of liquids and gases,in engineering units such as [mL/min], standard cubic feet per hour [scfh] etc. Such scales are designed exclusively for a specific gas or liquid at a given set of pressure and temperature parameters and are valid for the associated units of flow only. The convenience of direct reading scale designs should be weighed against the resultant limitations of applicability. Generally, direct reading scales are most suited to OEM applications.

  • Millimeter scales indicate the vertical position of the spherical float within the metering tube as the flow increases or decreases.
  • It is necessary to use flow tables or graphs supplied, to correlate float referenced readings with actual volumetric flow rates.
  • The advantage of Universal type scales is the ability to utilize the use of a given flow meter for a great number of different fluids at diverse pressure and temperature conditions, generally preferred in applications in laboratories, etc.


  • Meters are available with built-in needle valves (CV™), high precision metering valves (MFV™) with “non-rising stems”, or with no valves. The higher cost of MFV™ valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flowrates.
  • Generally, for gas metering it is recommended that valves are positioned at inlets (bottom) for liquids valves may be positioned either at inlets or outlets (top). For vacuum services, valves must be mounted at outlets. If unspecified at the time of ordering, meters will be shipped with valves mounted at the inlets
