FMG450 Over Gear Flow Meter

FMG450 oval gear flowmeter is a kind of Volumetric flow measurement is the use of a fixed small volume to repeatedly measure the volume of fluid passing through the flowmeter. Therefore, there must be a space that constitutes a standard volume inside the positive displacement flowmeter, which is usually called the “measurement space” or “measurement chamber” of the positive displacement flowmeter. This space is formed by the inner wall of the meter housing and the flowmeter rotating parts.

FMG450-A cast iron oval gear flowmeter is widely used in the measurement of various oils and liquids that do not corrode cast iron materials.
FMG450-E cast steel oval gear flowmeter is used for the measurement of high pressure and low corrosive liquid media.
LFMG45-Q cast iron oval gear flowmeter, the gear is aluminum alloy. It is used in the measurement of low viscosity, low corrosive (such as gasoline, etc.) liquid media.
FMG450-B, C-type stainless steel oval gear flowmeters are widely used in the measurement of liquid media with strong corrosive liquids, such as acids, alkalis, salts and organic compounds.
FMG450-L light oval gear flowmeter is widely used in the measurement of low corrosive liquid media, such as water and other liquids.

Accuracy class 0.5, 0.2 (generally work at -10°C~+60°C)
Use medium temperature: (ambient temperature can be -40°C~+50°C)
FMG450-A, B, E (-20°C~+60°C); under high temperature adjustment, the heat sink with high temperature can reach 60°C~200°C
FMG450-Q, L (-20°C~+60°C)
