Multi-Trans Smart Ecosystem Overview
The Multi-Trans Smart Ecosystem (MTSE) has been engineered to provide a cost effective solution for accurate (±0.50%F.S.) airflow measurement of up to three systems; perfect for air handling or rooftop units requiring supply fan array, return fan array, and outside air intake monitoring. The MTSE can receive pressure signals from each fan’s existing piezometer ring airflow measurement sensors provided by the fan manufacturer or from field installed airflow sensors. The MTSE can simultaneously measure up to four differential pressure points such as pressure drop across filters to aid in HVAC filter replacement, duct static pressure, and plenum pressure.
The summed (total) airflow rate of the individual arrays and the outside air intake ventilation rate is indicated on a 3.5-inch, Human-Machine-Interface (HMI) touch screen; individual airflow rate of each fan in an array is also accessible via touchscreen menus. The total airflow rate of each array is available to the Building Management System (BMS) via dedicated field selectable 0 to 10 VDC or 4 to 20 mA analog outputs and via field selectable BACnet®-MS/TP Master or Modbus® RTU Slave network communications.
The MTSE can accept a temperature input signal for each system (up to 3 total) for air temperature indication and air density compensation for standard or actual airflow calculations.
The MTSE can be configured at the factory for plug and play installation or can be field configured using the Setup Wizard. Available menus include flow measurement configuration using the “Super-K” which is based on known fan quantity and the balancing agents reading, eliminating time spent supplying system configuration parameters for setup (such as area factors, piezometer constants, etc.)
