FGElectromagnetic Flow Meter
for Non-Full Water
An electromagnetic flow meter that measures a wide range of flow rate from non-full water to full water.
As a drainage flow meter, it is suitable for the measurement of understanding sewage usage and drainage quantity as well as reducing sewage charges.
・Measures non-full water.
・Measures from high flow rate to low flow rate with a high degree of accuracy.
・Can be installed in the middle of piping or in discharge ends depending on the situation.
・Introduces a variable sampling method that is well-equipped to handle solid object falls and flow rate changes.
・Excellent durability under severe conditions because it has no moving parts.

*1: The maximum non-full water flow rate is a boundary guide between the states of non-full water and full water.
*2: Please contact us for details.
*3: Mount the upstream straight piping and the detector coaxially.
Make sure that the piping inclination in downstream is not lower than that of upstream.
*4: Per mille (‰) is a sign indicating parts per thousand.
