Power Consumption: Less than 20 W.
Protection Grade: IP68.
Connection Method: Flange or Thread with materials like 304, 316L, Hastelloy alloy, Titanium, etc.
Accuracy: ±2.5%.
Communication Protocols: Modbus (RS485/RS232), Hart.
Power Supply: 220VAC, 24VDC/12VDC, 3.6VDC.
Signal Output: 4-20mA, pulse, frequency.

Key Features:

Simple and robust structure with no moving parts, ensuring long service life.
Strong anti-interference capabilities for reliable measurement.
Compact and lightweight design for easy installation.
Wide measurement range and cost-effective installation, especially for large diameter pipes.

Installation Guidelines:

The installation position should be fully submerged in liquid.
Ensure easy measurement of the pipeline's internal diameter or perimeter with minimal ovality.
Maintain a straight pipe length of more than 10D upstream and more than 5D downstream, where D is the pipeline diameter.
Vertical installation is recommended, with the sensor aligned vertically with the axis and an angle of less than 5° with the cross-section.
Two sensor insertion methods: 1/4 or 1/2 of the pipe inner diameter.
Correctly weld the installed base on the pipeline and clean any welding slag.
Turn off the flow control valve or use low water supply pressure during installation.

Ordering Information: The document provides a selection guide for ordering, including options for diameter, structure, electrode material, power supply, output signal, communication protocol, and installation type.

Data Summary: A table compares common pipe inner diameters with average flow rates and volume flow rates, providing a quick reference for expected performance across different pipe sizes.
