Product Description
Product Package: MXT03 Host Unit + MXS05D Current Meter
Product Overview
The MXT03S series online flow monitor for drainage networks is a dedicated device designed specifically for monitoring flow in sewer systems. Featuring an ultra-low-power microcontroller, it operates on battery power and incorporates network communication, enabling real-time, online monitoring of water levels and flow rates without requiring external power supplies, fiber-optic links, or pole-mounted installations. It employs a single-point ultrasonic Doppler velocity sensor to measure liquid level and flow velocity upstream of the sensor, all while preserving the natural flow field.
Product Features
● In compliance with the SL651-2014 Hydrological Monitoring Data Communication Protocol – Communication Protocol
● Employs a 32-bit ultra-low-power microcontroller, with a standby current of less than 35 µA.
● Powered by a single-use, high-capacity battery; under standard operating conditions, the battery replacement cycle is no less than 2 years.
● IP68-rated design, resistant to water ingress;
● Explosion-proof rating: Exia IIC T4 Ga;
● The housing is made of 316 stainless steel, offering excellent resistance to corrosion, acids, and alkalis, as well as impact resistance, making it suitable for use in sewage networks.
● Onboard temperature and humidity sensor for continuous monitoring of the enclosure’s environmental conditions;
● Onboard attitude sensor: when the device is moved illegally, it automatically sends an alert to the platform.
● High measurement accuracy, wide measurement range; capable of measuring both weak and strong currents.
● Highly sensitive, with high resolution, and not limited by the minimum flow velocity.
● Fast response time, capable of measuring both instantaneous and average flow velocity;
● Measurement linearity, with no calibration curve required. K, C value;
● Supports remote parameter configuration and monitoring, as well as remote device maintenance.
● Supports on-site configuration and maintenance via Bluetooth;
● It adopts a modular design, allowing direct replacement of the communication module without replacing the motherboard.
