Thermal gas flow meter DN65-250 testo 6457
Testo SE & Co. KGaA
About This Product
Testo's thermal gas flow meter can measure the consumption of compressed air with high accuracy, identify leakage, identify the possibility of energy saving, and reduce costs. This thermal gas flow meter is suitable for the distributor DN65 to 250, so it can be used flexibly.
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 to save energy, reduce costs, and implement an environmental management system (ISO 50001 or ISO 14001, etc.) that focuses on the target.
･ Quick change fitting: Prove can be removed with pressure applied
･ Three 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 heat measurement principle, as small pressure loss as possible
･ Flexible: Configuring to DN65 to 250 for distribution.
