Product portfolio of Mass Flow ONLINE B.V.

MASS-VIEW series

The intelligent alternative for VA meters or purge meters: thermal Mass Flow Meters for gases with flow display and electronic output signal. Mass flow control through optional needle valve. Multi-range calibration for a number of standard, pre-installed gases.

Applications: measurement of gas consumption (hospitals), flow rate monitoring (laboratories), test equipment (production maintenance), cost center billing, burner control (furnace construction)

Full Scale ranges from 0.2 ln/min up to 500 ln/min N2-equivalent.

MAG-VIEW series

Magnetic flow meter for liquids. The complete absence of moving parts, its interference free operation and the insensitivity with contaminated liquids, makes MAG-VIEW™ the perfect solution even in compact machines with cramped confines.

Applications: continuously measurement of flow rates, dosing / batching of electrically conductive liquids with a minimum of 20µS/cm, water distribution, chemical feed.

Flow ranges from 0.1-2 l/min up to 12.5-250 l/min.

LIQUI-VIEW Base series

This instrument series operate on the vortex principle. The obstruction (bluff body) placed in the flow of the liquid sheds vortices downstream at a frequency proportional to the velocity of the liquid. The LIQUI-VIEW Base series offer a compact, light weight and cost-effective solution for monitoring the flow or consumption of cleansing, cooling or spa water.

Applications: Cooling water monitor, deionized water (RO/DI skids), ultra pure water distribution (medicare, biotech, semiconductor, pharmaceutical)

Flow ranges from 0.5-10 l/min up to 9.0-150 l/min.


Compact, non-obstructive ultrasonic flow meter for measuring water and aqueous solutions. Very low pressure drop due to straight, stainless steel sensor tube and no moving parts. May be mounted in any position. No straight inlet or outlet runs required. IP54 protected.

Applications: measurement of toxic liquids in chemical industry, cooling water, waste water, aqueous solutions, beverages, solvents.

Flow ranges from 1.5-30 l/min up to 5-110 l/min.


Designed for extremely precise control of a constant flow rate in low flow gas and liquid applications. The desired flow rate is set via the needle valve. Any upstream or discharge pressure variations are automatically compensated by a built-in membrane operated valve to ensure a steady, constant flow.

Applications: constant flow control of gases, constant flow control of liquids, process control, gas/liquid sampling, inert gas/liquid blanketing, pressure regulator of gas and liquids, maintaining constant flow rate, and diverse other applications.

Gas flow ranges up to 50 ln/min (N2)
Liquid flow ranges up to 1.8 l/min (water)
