Function & Performance Features

• Onboard two-line LCD local display with physical operation buttons, realize on-site zero calibration, range reconfiguration without standard pressure source
• Support linear output or square root extraction output for flow measurement
• Adjustable digital damping (0~32 seconds) to filter fluid pressure fluctuation interference
• Forward/reverse output signal configurable, flexible matching DCS system signal collection logic
• User-defined fault-safe output: High scale (21mA) or low scale (3.6mA) when sensor failure occurs
• External zero adjustment screw reserved for on-site fine-tuning in confined hazardous areas
• Dual seal isolation design, meet ANSI/ISA 12.27.01 process pipeline safety standard
• Strong anti-corrosion compatibility with water, oil, weak acid/alkali industrial media
• Multi-point temperature compensation circuit, eliminate measurement drift caused by ambient temperature change

Working Principle

Material & Structural Characteristics

1. Measuring Cell: 316L stainless steel isolation diaphragm, silicon pressure sensing core
2. Process Connection Body: Forged 316 stainless steel, 1/4 NPT pressure tapping port
3. Electronic Housing: Die-cast aluminum, epoxy coating resistant to salt spray and chemical corrosion
4. Display Window: Tempered scratch-resistant glass, anti-condensation coating
5. Internal Circuit Board: Anti-corrosion coated PCB, industrial grade low-drift operational amplifier
6. Mounting Accessories: Stainless steel pipe clamp bracket, support 2-inch pipeline mounting or wall surface installation

Installation Requirements

1. Can be mounted on vertical pipeline, horizontal pipeline or control panel wall; liquid medium installation requires transmitter below pipeline to avoid gas accumulation inside measuring cell
2. Pressure guiding pipeline needs to be equipped with drain valve and exhaust valve to eliminate liquid/gas accumulation
3. Electrical wiring uses shielded twisted pair cable, single-end grounding of shielding layer to reduce electromagnetic interference
4. Explosion-proof model wiring must use certified explosion-proof cable glands, seal cable inlet completely
5. Install bracket to fix transmitter firmly, avoid pipeline vibration causing long-term measurement drift
6. Ambient installation location avoid direct sunlight and open flame heat radiation

Application Scenarios

• Petrochemical pipeline flow and liquid level measurement
• Thermal power plant boiler water level, steam flow monitoring
• Water supply and sewage treatment differential pressure flow meter supporting measurement
• Pharmaceutical process tank liquid level and filter pressure difference monitoring
• Natural gas pipeline differential pressure flow detection
• Food & beverage production fluid pressure measurement

Operation & Maintenance Precautions

• Strictly prohibit overpressure exceeding MWP 3626 PSI, which will permanently damage isolation diaphragm
• Regularly exhaust gas from pressure guiding pipe to prevent gas lock affecting accuracy
• Do not disassemble measuring cell body privately; disassembly will destroy internal filling fluid seal
• Avoid strong mechanical impact on transmitter housing during transportation and installation
• When measuring corrosive media, replace wetted parts with Hastelloy or Tantalum material version
