Installation direction: Horizontal or vertical installation (gear shaft must be horizontal)

Front and rear straight pipe sections: upstream≥5D, downstream≥3D（DFor the inner diameter of the pipeline)

electrical connection

Cable interface:M12x1Circular connector（IP67Protection)

Shielding requirement: The signal cable needs to be twisted pair shielded (grounding resistance)<10Ω）

Precautions for use

Media filtration must be installed25μmPrecision filter (recommended)10μm）

The initial use of the startup process requires exhaust first (slowly increase the pressure to2 barThen fully open the valve

Maintenance cycle every5000Check the seals hourly,10000Replace bearings every hour

When the fault handling pulse signal is lost, priority should be given to checking the polarity and grounding of the power supply

When the storage conditions are not in use, anti rust oil should be filled and the environmental humidity should be maintained≤85%, non corrosive gas

Selection suggestions

When the following conditions are met, it is recommended to prioritize selecting this model

The flow range is0.1-0.5 L/minInterval and require high-precision measurement

The temperature of the working medium exceeds80°COr lower than0°C

There is strong electromagnetic interference in the system (such as near the variable frequency motor)

Long term unattended operation is required (average time)>30000Hour)
