Instrument Overview

Product Features

Combines flow rate, water level, and water temperature parameters; features automatic calibration at low flow rates; uses lead fish for high-flow-rate applications; incorporates anti-corrosion nanotechnology; measures water level via pressure sensors; supports multiple communication interfaces.

Technical Parameters

Flow rate frequency	5MHz
Flow rate range	0.02–7.00 m/s
Flow rate accuracy	1.0% ± 1 cm/s
Flow rate resolution	1mm/s
Water level range	50m pressure-type
Water level accuracy	±0.5%FS
Water level resolution	1mm
Water temperature range	-5℃~40℃
Water temperature accuracy	±0.5℃
Water temperature resolution	0.01℃
Depth of immersion	50-meter water area (other ranges available upon customization)
Measurement mode	Automatic and manual two types
Measurement interval	Automatic mode: Select a value from 0 to 120 minutes, with a minimum increment or decrement interval of 5 minutes. Manual mode: Measurements can be taken once or multiple times in succession, with any desired interval.
Speed measurement duration	Automatic modes: two options—60 seconds and 100 seconds. Manual mode: 10–120 seconds, with incremental or decremental selection.
Working power	External DC 12V power supply
Output interface	RS232 by default, other customizations available
Protection level	Probe IP68, handheld or wall-mounted host IP65
Water flow direction identification	The flow velocity probe automatically identifies the direction of water flow and can rotate freely within an azimuth range of 0–360 degrees. When the flow velocity exceeds 0.5 m/s (or 1 m/s), a lead fish device can be suspended from it.
