The engineers at a large food industry vegetable drying plant processing onions recently needed better humidity control to avoid batch recycling due to the variable moisture content of the onions and other vegetables. FCI’s ST50 Series Thermal Air/Gas Flow Meters were placed in multiple locations (inlet pre-heated air, re-circulation air, outlet), allowing the plant team to adjust air flow rates throughout the process depending on onion humidity levels, which ensured drying of the onions by the end of the process–with minimal batch recycling, states the company.

The installation of flow meters in the process control loop for air blower and dryer systems provides highly accurate hot air flow rate monitoring. The use of mass flow meters ensures precise rate of flow measurement and totalized flow measurement for zone control and overall system operational efficiency. In addition, they can accurately measure and control and/or sub-meter natural gas flow to heaters and burners, which cuts plant energy operating costs while reducing a plant’s carbon energy footprint and increasing competitiveness, adds the firm.

Relying on FCI’s highly accurate thermal dispersion mass flow sensing technology, the flow meters provide accurate and repeatable direct mass flow measurement at a lower cost. With the ST50 meter, there is no need for the temperature sensors, flow computers or the other devices required with orifice plates, Venturis, Vortex shedding and other flow meters. The flow meters’ unique design also provides built-in temperature compensation for reliable measurement over a wide temperature range with almost no pressure-drop, mentions the company.

There are two process connections options available for the ST50 meter: 1/2-inch MNPT or 3/4-inch MNPT with a stainless steel or Teflon ferrule. It is available in three field adjustable U-length probes: 1-6 inches (25-152mm), 1-12 inches (25-305 mm) and 1-18 inches (25-457mm) for pipe sizes 2 to 24 inches (51 to 610mm).
