  2. 2. MODE/ENTER SET Decentralised monitoring, measurement and display of compressed air consumption. Many sources, including the cam- paign ”efficient compressed air“* clearly indicate the growing interest in the optimised use of the energy carrier compressed air. This is a sub- stantial saving potential for operating costs. efector metris helps to explore this potential. Measurement of compressed air consumption Optimised consumption of compressed air Allocation of consumed quantities The integral 4-digit LED display plus the status LEDs allow infor- mation to be avail- able at the point of monitoring. Whether peak consumption, present or accu- mulated consump- tion: Set switch or alarm levels can be accessed and programmed via pushbutton. All settings can be protected using the electronic lock function. 8 Nm3/h 12 Nm3/h 5.5 Nm3/h * See

Thus the consumption can be allocated to production processes or prod- ucts for optimising cost structure. Decentralised location of efector metris in the sup- ply pipe to the individual machine unit. Location of efector metris in the supply pipe prior to distribu- tion to several installations or machine units. Leakage monitoring Two reliable indications of air leakage are the increase in consumption of com- pressed air with unchanged machine load and the continuing consumption of compressed air when the machine is no longer in operation. Leakage at a glance. The compressed air meter´s integrated pipe length ensures easy mounting and high measurement accuracy. Easy to mount in the supply system. R Annual energy costs due to leakage: kWh x 0.06 EUR x 8000 operating hours/a.; Source:
  4. 4. MODE/ENTER SET From now on: Accurate monitor- ing of compressed air consump- tion with efector metris. The low purchase price makes it possible: To measure compressed air where it is used. Even very small leaks are detect- ed and can be repaired in good time. The quantities consumed can be directly allocated to the relevant production units. In situ display of total or current consumption. Switching, pulse or analogue outputs for further external processing. Determine maintenance intervals depending on consumption. Measurement free from pressure loss due to a special design of the measuring probes. Response time in the millisecond range. Calorimetric measuring principle Integrated display for direct indication of consumption. Even small leaks can cause unneces- sary electricity costs of several thousand Euro per year. The calorimetric principle measures the standard volume flow irrespective of temperature and pressure – quickly and over a wide measuring range. Leakage detection, energy cost reduction and environmental protection.
