Flush Type Pressure Transmitter
Introduction
A flush-type pressure transmitter is specially designed for measuring pressure in challenging applications, such as those involving highly viscous or solid-laden fluids. Unlike traditional pressure transmitters, flush-type pressure transmitters feature a diaphragm that sits flush with the device's front, preventing debris buildup and contamination.
Features of Flush Type Pressure Transmitter
• Precise & accurate
• Flush Diaphragm process connection
• Wide range compatibility
• Fully welded design
