Product Applications
  • Fine Chemicals and Pharmaceutical Plants: For reaction vessels and raw material tanks. This module supports the HART protocol, facilitating remote calibration and intelligent diagnosis by the factory through the upper computer system (such as 800xA).
  • Oil and Gas (Storage and Refining): In the storage tank area of the refinery, the M4A-AT is combined with the AT100 transmitter to monitor the precise liquid level and interface of crude oil, refined oil products, or liquefied gases. Its high precision (up to 0.01%) is crucial for trade settlement and inventory management.
  • Power and Boiler Systems: In pressure vessels such as feedwater heaters and condensers in thermal power plants, the M4A-AT can provide stable liquid level data in high-temperature and high-pressure environments, ensuring process safety.
  • Water Treatment and Environmental Protection Plants: For large water tanks and chemical storage tanks, for liquid level control, especially in automated pumping stations that require non-contact or high-reliability measurement.
