AWF410 Series

AWF410 series features in dual-channel ultrasonic time difference method & dynamic zero point design, making the measurement more accurate and reliable. It uses stainless housing and absence of moving parts resulted in high stability. The flow stabilization function endows the meter with stable measurements and immune to the influence of flow field. With few requirements for straight pipe distance, the water meter has strong practicability. The Low power consumption design results service life up to 15 years. Besides IP68 waterproof design, it is with MODBUS, pulse, and current output is optional. It is widely used in industry, agriculture, waterworks and other fields.
