• Aluminium or stainless steel construction
• Easy maintenance
• Model L flowmeter for flow rate setting and monitoring

Typical applications

• Water purging for instruments
• Air purging in level measurements
• Gas purging in Δp measurements
• Hydrostatic density measurements

Options

• Flow alarm
