Model Description
Product details
Testo's thermal flow meter can perform accurate compressed air consumption measurement, consumption and leakage, and flow measurement in the compressed air system. This thermal gas flow meter can also be used for peak road analysis to determine whether sufficient capacity compressed air is generated. This creates transparency in consumption of compressed air, which helps the implementation of energy savings, cost reductions, and the implementation of an environmental management system (ISO50001 or ISO14001, etc.) that focuses on the target.
testo6457 Technical merit of thermal gas flow meter
• Quick change fitting: Prove can be removed with pressure applied
• 3 measurement items (flow rate, integrated value, temperature) can be confirmed simultaneously
• Easy -to -view display: TFT display is standard equipment, displayed three measurement values at the same time, and directly monitor compressed air.
• Best system integration: pulse and analog output
• Instead of pressure loss due to heat measurement principles
• Flexible: Configuring to DN65 to 250 for distribution.
