Measuring principle

Oval gear

Type of sensor

Hall effect (Transistor output) or Reed contact (Reed switch output)

Measuring range

0.5…500 l/h (0.13…132 gph) (depends on the variant)

Standard K factor

• For flow range 0.5…100 l/h: 1000 pulses/l

• For flow range 15…500 l/h: 400 pulses/l

Performance data

Measurement deviation

• Standard K factor: ± 1 % of the measured value

• Specific K factor (directly readable on the label of the product): ± 0.5 % of the measured value

Repeatability

≤ 0.03 % of the measured value
