A Measurement Setup

No.	Name	Description
A02	Pipe Type	Select the pipe standard used by the flowmeter. Default: custom.
A03	Pipe Geo. Unit	Set the pipe unit. Default: mm.
A04	Pipe OD	Set the pipe outer diameter. Default values vary depending on the selected pipe unit.
A05	Pipe Perimeter	Set the pipe circumference. Default values vary depending on the selected pipe unit.
A06	Pipe thickness	Set the pipe wall thickness. Default values vary depending on the selected pipe unit.
A07	Pipe ID	Set the pipe inner diameter. Default values vary depending on the selected pipe unit.
A08	Pipe Material	Set the pipe material. Default: custom.
A10	Liquid Type	Set the liquid type. Default: custom.
A12	Liquid Soundspeed	Set the liquid Soundspeed. Default: custom.
A13	K.Viscosity cst	Set the fluid dynamic viscosity. Default: 1.
A15	Damping	A15 Damping: Smooths flow measurement data. Default: 3. Higher value → smoother display, smaller fluctuations, slower response. Lower value → faster response, more sensitive to flow disturbances, larger fluctuations.
A16	Direction	Reverse flow definition. Default: normal flow.
A17	Neg Flow (Negative Flow)	Enable display of reverse flow. Default: on.
A18	Low flow cutoff	Low-flow cutoff: displays flows below the set value as zero. Default: 0 (off).
A19	Fast Update	Screen refresh rate: allows updates every 0.5 s. Default: off.
A20	Anti-Noise	Noise elimination for unstable measurements. Default: on, can be disabled.
A21	Auto Initialization	Auto-detect fluid ultrasonic velocity to complete environmental parameter setup after installation and parameter configuration.
A22	Auto Zero Offset	Auto zero calibration: resets the flowmeter output to zero. Recommended for very low flow measurement to correct zero offset errors.
A23	Zero Offset	Manual zero compensation: corrects internal system time offset. Unit: ns (not a flow unit). Refer to the value on the User Debug Page and input into A23.
A26	Beta Mode	A26: Default off. Not fully tested; do not enable.
