Newly enhanced multi-channel, multi-parameter controller with BTU calculator

June 19, 2006

GF Piping Systems has enhanced the Signet 8900 Multi-Parameter Controller with a BTU calculator to provide high accuracy measurement of energy and power consumption. The new feature broadens the unit’s application range to include a variety of HVAC applications such as heat transfer systems, central plant monitoring, chilled water systems, and hot water heating systems. Other important performance characteristics include international language display and excellent signal integrity for long-distance cable runs connecting to remotely located sensors. The new BTU calculator brings with it a wide range of high-performance capabilities designed to save time and provide user flexibility. The unit can execute two simultaneous BTU calculations–heating and cooling, two cooling, or two heating. With its ability to compute and store calculations, users have immediate access to all the energy data they need and can easily pull up stored data from previous dates for comparison. The 8900’s BTU calculator also allows user-selection of up to nine heating and cooling totalizer units and up to six power units, enabling control of multiple measurement data with just one economical device. Other features include programmable density and heat capacity parameters to ensure high accuracy and use of Power value, Flow Rate and Delta Temperature values to source 4 to 20mA or relay outputs.
