Emerson Rosemount 08800-0250-0001 Piezoelectric Vortex Sensor for 8800 Series Vortex Flowmeter

Product Description

08800-0250-0001 is the OEM piezo sensor assembly manufactured by Emerson Rosemount, designed exclusively for Rosemount 8800D vortex flow meters. This is the core sensing element that detects vortex shedding generated by fluid passing through the bluff body inside the flow tube. It converts the pressure pulses created by vortices into electrical signals for flow rate calculation. This high-temperature variant sensor is used for liquid, gas and steam flow measurement. It is a common spare replacement component for petrochemical, power and oil & gas flow measurement loops.

Key Functions

• High-sensitivity piezoelectric sensing element to capture vortex pressure pulses generated by flowing media
• Converts fluid vortex events into proportional electrical frequency signals; transmitter calculates volumetric flow rate based on pulse frequency
• Extended temperature version, operating range: -40 °C ~ +120 °C; compatible with liquid, gas and saturated steam service
• High frequency response range 0.5Hz ~ 5kHz, sensitivity 100mV/g; resonant frequency 25kHz
• Sealed, rugged stainless steel assembly; resistant to process pressure, vibration and fluid noise interference
• Direct replacement spare for 8800D vortex meter; installs into the vortex meter head, interfaces with the flow transmitter electronics
• Immunity to pipeline vibration; built-in noise filtering to suppress mechanical vibration signals from process piping

Application Scenarios

• Rosemount 8800D series vortex flow meter spare piezo sensor assembly
• Petrochemical, refinery, power plant, chemical process flow measurement: liquid, gas and saturated steam flow monitoring
• Industrial process skids, energy management, utility steam / compressed gas flow metering
• Field maintenance and replacement for existing installed Rosemount vortex flow meters

Common Issues & FAQ

• No flow reading / zero signal: Check sensor wiring and connector integrity; verify sensor installation depth and seating; inspect for mechanical damage to the piezo crystal; confirm fluid velocity is above the meter low flow cutoff threshold.
• Unstable / noisy flow readings: Check for pipeline vibration interference; inspect sensor for moisture ingress or seal leakage; verify if process fluid contains solids that may damage the sensing tip.
• Flow reading drifts after temperature swing: Confirm this sensor temperature rating matches actual process media temperature; inspect sensor cable insulation degradation under high temperature service.
• Refurbished / replacement unit note: After installing the new piezo sensor, perform sensor zero calibration in the transmitter, validate flow signal output, test for vibration interference and perform loop HART communication check before returning the meter to online process service. Confirm part number compatibility with your specific 8800D meter body and transmitter firmware.
