Siargo Mass Flow Sensors

AM1000 Series MEMS Environmental Meter

The AM1000 Series is designed for air velocity measurement in a closed conduit or open space, with optional temperature and humidity sensing data (AM1100 model). The sensing elements are made on a specially designed MEMs structure that enhances the measurement accuracy and response time while lowering the power consumption. The RS485 (Modbus) and Bluetooth LE options are ready for networking or remote communication. This format is ideal for residential HVAC or smart home applications.

The product is fully customizable for flow ranges and user interfaces and can be packaged into a complete meter with local display or with a standalone battery power unit.
