From Malema Sensors
 

 

Malema's M-VF Series adjustable velocity fuse is a safety device used in tubes and pipe lines carrying hazardous and expensive fluids. A rupture or leak in these tubes/pipes causes the velocity of the fluid to increase beyond a predetermined set level causing the fuse to shut off the line.

All refineries and various petrochemical and chemical plants use process gas analyzers such as gas chromatographs and TOC analyzers. Hydrogen is used as a carrier gas in gas chromatography and in various analytical instrument applications, most commonly as a fuel component of combustion gases for Flame Ionization (FID) and Flame Photometric (FPD) detectors. Spark discharge analyzers, total hydrocarbons measurements also use hydrogen mixtures. Using hydrogen as a carrier gas speeds up the process of analyzing the component.

Products & Services
Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes. These devices consist of a chamber that obstructs the media flow and a rotating or reciprocating mechanism that allows the passage of fixed-volume amounts.
Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases.
A mass flow meter is a device that consist of a mass flow sensor or transducer and signal processing electronics.  Fluid (liquid or gas) flow is measured in mass rate units (lbs/min).
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.
