Chongqing Chuanyi MTP Series Submersible Hydrostatic Level Transmitter

The Chongqing Chuanyi MTP Series Submersible Hydrostatic Level Transmitter represents a highly reliable and cost-effective solution for continuous liquid level monitoring in industrial automation. Operating on the hydrostatic pressure principle, the device calculates fluid level using the fundamental formula where pressure is directly proportional to liquid depth and density.

Advanced Hydrostatic Sensing Principle The instrument features a high-stability piezoresistive pressure sensor housed within a rugged stainless steel enclosure. When lowered into a liquid vessel, well, or open reservoir, the liquid pressure acts directly on the sensor diaphragm. A specialized cable equipped with an internal vent tube ensures continuous atmospheric pressure compensation, effectively eliminating ambient barometric pressure fluctuations to guarantee accurate level readings.

Robust Design and Long-Term Stability Designed for deep submersion and harsh environments, the MTP series incorporates advanced sealing technology and corrosion-resistant wetted materials. Its solid-state construction contains no moving parts, preventing mechanical wear and ensuring exceptional long-term stability even when deployed in municipal water systems, storage reservoirs, or industrial wastewater pits.

Seamless System Integration Equipped with standard industrial output signals (such as 4-20mA), the transmitter connects effortlessly into existing Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), and remote telemetry units (RTUs). Its simple drop-in installation makes it an ideal choice for rapid deployment in deep wells and complex tank geometries.
