Brief Introduction

The flush diaphragm pressure transmitter through direct mounting on pipes or vessels, delivers reliable performance in harsh environments. The diaphragm seal pressure transmitter’s design allows direct contact between the isolation diaphragm and the liquid medium, eliminating the need for a pressure-guiding tube. Thus, the capillary level transmitter is ideal for measuring the level, pressure, and density of mediums with high temperature, high viscosity, tendencies to crystallize, precipitate, or cause corrosion. The differential level transmitter generates a 4-20 mA DC output signal that is highly compatible with control systems, providing real-time monitoring capabilities. Additionally, the pressure transmitter with diaphragm seal is equipped with a standard flange, ensuring easy installation and a secure connection to process vessels or pipes.

The pressure transmitter with diaphragm seal is a versatile device used in various industrial environments to measure liquid level, pressure, and density accurately. Capillary level transmitter's robust design and direct diaphragm contact with the medium make it well-suited for a range of challenging conditions.

Industry application

Oil and Gas Industry - In oil and gas separation, tank level monitoring, and downhole operations, the flush diaphragm pressure transmitter handles high-pressure and high-temperature environments, while also accommodating viscous media and corrosive gases common in oil fields. Capillary level transmitter's durability and remote monitoring capabilities support precise data collection on offshore platforms, pipelines, and refineries.

Chemical Industry - This field often involves acidic, alkaline, and highly corrosive media. The diaphragm seal pressure transmitter's direct contact design provides accurate measurements while avoiding corrosion issues associated with traditional pressure-guiding tubes. Flush diaphragm pressure transmitter is particularly suitable for measuring crystallizing and precipitating liquids, such as saline solutions and acidic or alkaline solutions.

Pharmaceutical and Food Industry - In pharmaceutical and food processing, strict sanitary conditions are required. The differential level transmitter's design without a pressure-guiding tube reduces contamination risk and is easy to clean. It effectively measures high-viscosity fluids such as syrups, concentrates, and emulsions, meeting CIP (Clean-in-Place) and SIP (Sterilize-in-Place) requirements to ensure hygiene and safety.

Water and Wastewater Treatment - The capillary level transmitter is used in wastewater and water treatment plants to monitor levels and pressure, handling media with suspended solids and sediments. Its corrosion-resistant design adapts well to chemical treatments in water, providing stable support for quality control and monitoring.

Power Industry - In power plants, this pressure transmitter with diaphragm seal is used for boiler water level monitoring and coolant monitoring. Its high-temperature tolerance and stability make it widely applicable in power systems, ensuring safe and efficient equipment operation.

Pulp and Textile Industry - For slurries and fiber-containing liquids, the capillary level transmitter avoids the issue of tube blockages. diaphragm seal pressure transmitter is effective in the pulp and textile industries, enabling monitoring of slurry concentration and levels, which helps optimize production processes.
