Technical Field
[0001] The utility model relates to the field of flow meters, in particular to a steel-plastic casting integrated flow meter. Background Art
[0002] The flowmeter's operating principle is that liquid passing through the meter drives the internal gears, which intermittently generate magnetic signals. The Hall effect sensor in the circuit captures these signals and transmits them as light feedback via the M3 signal. Traditional steel flowmeters are difficult to machine, making cavity fabrication labor-intensive and time-consuming. Even readily machineable materials are either corrosion-resistant or incapable of withstanding high pressures.
