Overview

Based on high-precision hydraulic sensing principles, it monitors the real-time pressure difference of the liquid before and after pipelines and equipment, accurately providing feedback on operating conditions such as pipeline blockage, filter screen buildup, slurry viscosity, pump malfunction, and pipeline pressure drop imbalance. It provides core data support for pump frequency conversion control, pipeline blockage early warning, water circulation flow regulation, and slurry filtration condition diagnosis. It effectively avoids problems such as pipeline blockage, flow attenuation, pump overload, and decreased heat exchange efficiency, making it a core liquid monitoring instrument for stable circulation, unobstructed pipelines, and intelligent management of desulfurization and dust removal water systems.

Features

Employing an industrial-grade high-precision liquid sensing core, this sensor offers sensitive and accurate differential pressure detection with a fast response time. It can capture minute changes in liquid pressure differences, updating data in real-time without lag or deviation. It accurately reflects the pressure drop conditions in slurry and water circulation pipelines, providing reliable data for intelligent system control of pump frequency and troubleshooting of pipeline blockages.

Specifically designed for industrial liquid conditions, the probe uses corrosion-resistant and scale-resistant materials, exhibiting excellent resistance to slurry buildup, impurity erosion, and acid and alkali corrosion. It can be used long-term in complex liquid environments such as desulfurization viscous slurries, wastewater containing impurities, and corrosive circulating water. The sensing surface is resistant to scaling and corrosion, and its measurement performance does not degrade over time.

Extremely stable operation, unaffected by fluctuations in liquid flow rate, slurry bubbles, temperature changes, or electromagnetic interference. There is no data drift or numerical fluctuation. Whether in high-flow-rate dynamic water delivery conditions or low-flow-rate stable-pressure slurry conditions, it maintains accurate and stable differential pressure data output.

Equipped with a standard 4-20mA analog signal output, it can seamlessly connect to PLC and DCS automation control systems, enabling automatic alarms for excessively high and low hydraulic differential pressures, frequency conversion linkage of water pumps, early warning of pipeline filter blockage, and intelligent water circulation control, significantly improving the automation and intelligent operation and management level of the desulfurization and dust removal water system.

The entire unit adopts an integrated waterproof, dustproof, explosion-proof, and corrosion-resistant structural design. The robust shell is resistant to aging, vibration, and humid and corrosive environments, making it suitable for harsh working conditions in plant areas with high humidity, dust, and complex electrical systems. It supports 24-hour continuous operation, has no delicate or easily damaged structures, and has an extremely low failure rate.

Suitable Scenarios

Widely compatible with various liquid differential pressure monitoring scenarios in desulfurization and wet electrostatic precipitators, including slurry pipeline differential pressure, circulating water inlet and outlet differential pressure, filter screen differential pressure, heat exchanger hydraulic differential pressure, and wastewater pipeline pressure drop monitoring. Primarily used in wet desulfurization and dust removal processes in thermal power generation, heating, metallurgical sintering, cement kiln tail, chemical tail gas, and waste incineration, this instrument is essential for industrial water system pipeline condition diagnosis, anti-clogging early warning, and water circulation pressure stabilization.

Maintenance Design

The equipment comes standard with a hydraulic differential pressure sensor, dedicated liquid pressure guide connector, anti-clogging sampling device, fixed mounting bracket, and sealed wiring accessories, offering a complete set, simple installation, and wide versatility. It supports multiple range selections for micro, medium, and high differential pressure, and can be matched with conventional, corrosion-resistant, explosion-proof, and anti-clogging models based on slurry concentration, water impurities, pipeline pressure, and corrosion conditions. It is compatible with both new and upgraded desulfurization and wet electrostatic precipitator water systems. Daily maintenance is simple, requiring only periodic cleaning of accumulated impurities at the sampling port and calibration of measurement values, resulting in extremely low long-term maintenance costs.

Note

Liquid differential pressure transmitters are designed for accurate monitoring of pipeline hydraulic differential pressure and intelligent early warning of sludge and blockage. They are the core instruments for the operation and maintenance of desulfurization and dust removal water system pipelines. Scale and impurities at the sampling port can lead to inaccurate data and misjudgment of operating conditions. Regular cleaning and dredging and parameter calibration are required to ensure smooth water circulation pipelines and stable operation of the water pump system.
