Air Flow Monitor EWA2 SERIES Conforming to EMC Directive (all models) & Pressure Equipment Directive (AEWA2150/2200 only) Visualize Nitrogen Gas Consumption as Well as Air Consumption! Small pipe size Medium pipe size Large pipe size Ultrasonic type
Open the catalog to page 1Visualize Compressed Air and Nitrogen Gas (N2) Reducing power consumption in a factory starts with the identification of waste. Waste can be fairly obvious in cases such as air conditioning and lighting, however, hidden sources of waste may exist in the use of air within the factory. By visually detecting how compressed air and nitrogen gas are wasted, a plant operator can repair and eliminate the source of the loss. Resistant to oil mist and maintenance-free! Small pipe size: 25A or 32A Medium pipe size: 40A, 50A, 65A or 80A Large pipe size: 100A, 150A or 200A Four features of Air Flow...
Open the catalog to page 2Consumption in order to Identify and Eliminate Waste! What does this figure mean? Ratio of power consumption app. by compressors to the total power consumption at factories Compressors typically require more electricity to run than other equipment. Reducing the power consumption of air compressors should be a key target of any energy savings plan. Moreover In general, air leakage accounts for up to Others Lighting Production equipment Visualize Air Consumption to Identify and Eliminate Waste! (Breakdown of the power consumption by a typical factory) Install the ultrasonic type Air Flow...

Open the catalog to page 4Application example 2 Setting/monitoring using Programmable Display GT Series By connecting to the Programmable Display GT, Air consumption can be checked from a distance. You can achieve “Visualization” without using a PC as a display or Data logger for collecting data. Use in combination with the Eco-POWER METER and KW Watcher to visualize the all aspects of energy usage in one place. 1. Connect the pulse output of Air Flow Monitor to Eco-POWER METER. 2. Display graphs of electricity, temperature, compressed air and nitrogen gas usage, and other data as collected by the Data Logger Light...
