SKC
Our SKC precision monosilicon differential pressure transmitter is purpose-built for high-accuracy flow, level, density, and differential pressure measurement in critical industrial process systems. Equipped with advanced mono-silicon sensing technology, this high-performance transmitter delivers ultra-fast response, seamless remote configuration, and intelligent self-diagnosis for liquids, gases, and vapors. Supporting HART, FF fieldbus, PROFIBUS PA, and APL communication protocols, with optional TÜV SIL3 certification per IEC61508, the device is tailored for reliable, repeatable measurement for flow measurement and differential pressure control. With a market-leading turndown ratio of up to 100:1, it adapts to variable process conditions with consistent precision.
The transmitter delivers a standard reference accuracy of ±0.05%, with a high-accuracy option of ±0.035%, paired with exceptional long-term stability of ±0.1% over 10 years. This minimizes calibration frequency, reduces maintenance costs, and ensures consistent performance over the device’s service life, making it ideal for custody transfer flow measurement and critical process control.
Engineered for seamless integration with differential pressure primary elements (orifice plates, venturi tubes, flow nozzles), the transmitter features a high-pressure side capillary design for cost-effective installation and reliable flow measurement performance. It supports real-time differential pressure tracking for filter clogging detection, pump health monitoring, and pressurized tank level measurement.
To handle corrosive, high-temperature, and aggressive media, the transmitter offers a wide range of wetted material options. Isolating diaphragms are available in 316L SST, Hastelloy® C-276, 316L SST + Au coating, Tantalum, Titanium, and Nickel, with sensor body options in 316 SST and Hastelloy® C-276. Fill fluids include silicone oil and fluorinated oil for specialized process requirements.
The transmitter housing is available in aluminum alloy or 316 stainless steel, with cable entry options of ½-14NPTF or M20×1.5 female thread to fit global installation standards. Capillary tubing is manufactured from 316 SST, with optional stainless steel or PVC-coated armor for mechanical protection in harsh plant environments.

Our flow measurement differential pressure transmitter is deployed across a wide range of industrial sectors:
Oil & Gas: Custody transfer flow measurement, wellhead differential pressure monitoring, pipeline flow tracking
Chemical & Petrochemical: Reactor feed flow measurement, filter differential pressure monitoring, pressurized tank level measurement
Power Generation: Boiler feedwater flow monitoring, steam system differential pressure tracking, pump health monitoring
Water & Wastewater: Distribution network flow measurement, filter clogging detection, lift station differential pressure monitoring
Pharmaceutical & Biotechnology: Hygienic flow measurement for batch processing, CIP system differential pressure tracking
For flow measurement applications, mount the transmitter in line with the differential pressure primary element, ensuring equal length capillary tubing on high and low-pressure sides to minimize temperature-induced errors. Apply thread sealant to ½-14NPTF or M20×1.5 connections, with proper grounding for hazardous area installations. For liquid level applications, mount the transmitter at or below the lower tank connection to eliminate hydrostatic offset.
Use a HART communicator or remote software to set measuring ranges, perform zero calibration, and configure flow conversion parameters for your specific primary element. The built-in self-diagnosis system provides real-time fault alerts to reduce unplanned downtime. The fully modular design enables simplified on-site maintenance, with replaceable sensing and electronic modules without full device removal. We offer a 12-month standard warranty, with full lifecycle after-sales support.
