Особенности

• Measures energy rate and total consumption with highest accuracy available
• Accurately measures at both low flow rates and low differential temperatures
• Easy installation; no need to cut pipe or stop flow
• Minimal maintenance; external transducers do not require periodic cleaning
• No moving parts to foul or wear
• No pressure drop or energy loss
• Wide turn-down ratio
• Choice of single or dual channel / dual path or dual mode operation:
  • Dual channel operation reduces the cost for the system on a per channel measurement basis and permits measuring hot and chilled water lines at the same time
  • Dual path capability insures high flow measurement accuracy on installations with less than desirable piping runs
• Ability to operate in either Wide-Beam Transit-time or reflexor (Doppler) mode for applications with high aeration
• Zeromatic Path automatically sets zero without stopping flow and reduces zero drift, even at low flow
