The core value of customized design

To cope with some special working scenarios, PESCO provides customized services through modular design and technological innovation. Taking material upgrades as an example, the corrosion resistance of Hastelloy or titanium diaphragms can extend the service life of equipment in chemical environments; transmitters with IP68 protective housings and special sealing processes can operate stably in deep sea or high-humidity environments. Range customization breaks through the limitations of standard products. Whether it is 0-100Pa micro-pressure measurement or 0-40MPa high-pressure monitoring, precise adaptation can be achieved by adjusting the sensor structure.

Functional integration further expands the application scenarios. In hazardous areas such as refineries, transmitters with built-in explosion-proof certification (such as ATEX/IECEx) can ensure safe operation; for remote monitoring needs, the addition of wireless transmission modules (such as LoRaWAN) allows data to be synchronized to the control center in real-time. A chemical plant once faced the problem of concentrated sulfuric acid flow monitoring. By customizing the solution of Hastelloy diaphragm and polytetrafluoroethylene seal, the equipment life was increased by 3 times and the annual maintenance cost was reduced by 40%.

The key to successfully customizing differential pressure transmitters lies in accurate demand docking and rapid response. Customers need to clearly define the physical and chemical properties, environmental conditions, and installation restrictions of the measuring medium, and we match the optimal solution through simulation tests and experience databases. For example, an offshore oil and gas company needs to monitor the pressure changes of submarine pipelines. We customize titanium alloy housings, pressure compensation algorithms, and anti-salt spray coatings to enable them to work continuously for 5 years without failure in a 200-meter deep sea environment.

Traditional sight glass cleaning often requires interrupting the production process and disassembling the pipeline, which is time-consuming and labor-intensive. The PESCO sight glass adopts a modular structure. The operator only needs to loosen the safety buckle or flange bolt to easily remove the window glass and directly wipe the residual sediment, crystals or dirt inside. This design not only simplifies the cleaning process, but also avoids the risk of seal wear or leakage caused by frequent disassembly of the pipeline.

In addition, the PESCO sight glass adopts high-transmittance and corrosion-resistant glass and double sealing structure to ensure stable sealing performance and observation clarity after multiple disassembly. User feedback shows that this design reduces daily maintenance time by nearly 50%, and is particularly suitable for fluid environments that are prone to crystallization, high viscosity, or contain particles.

“The detachable function of the PESCO sight glass completely solves the cleaning problem and ensures production continuity and safety.” – Equipment Manager of a Pharmaceutical Company

As an innovator in the field of industrial fluid monitoring, PESCO has always been user-oriented and helps companies improve operation and maintenance efficiency through reliable and flexible designs.

Principle of Operation

How Coriolis Effect is Utilized

Coriolis Mass Flow meters operate by channeling the fluid through a vibrating tube. As the fluid moves, it experiences Coriolis forces, which cause the tube to deform. This deformation is directly proportional to the mass flow rate of the fluid. By measuring the degree of tube deformation, the meter can accurately determine the mass flow. This method ensures that the measurement remains unaffected by changes in fluid properties, such as viscosity or density.

Benefits of Direct Mass Measurement
