HVAC Bulk Water Process Control

		Bulk water storage tanks are used in conjunction with large HVAC installations to generate chilled water, resulting in better building temperature control. The chilled water is used to cool and dehumidify HVAC air in sizable commercial, industrial, and institutional facilities. Bulk storage water tanks can also serve to provide some or all of the buildings fire protection water storage. At this facility, the chilled water storage system cools water at night using off-peak electricity. In this application a relatively standard chiller is run at night to produce an ice pile. Water is circulated through the ice pile during the day to produce chilled water that is then used for heat exchange to provide cool air for the buildling.
The EchoSonic II ultrasonic transmitter chosen for bulk water tank measurement automatically compensates for temperature allowing for accurate measurement. In addition, EchoSonic II level transmitters have broad application. They can also be used for measurement of corrosive, ultrapure, and dirty liquids by performance optimization through Digital Signal Processing, or DSP. The EchoSonic^® transmitter's DSP, auto-adaptive filter enable any operator with plug and play installation, simplified and optimized signal output filtering as well as obstacle recognition, decreasing false signal detection for high or low water storage levels.
