Description
TL;DR
A sand probe is a pipeline sensor that detects sand production in oil, gas, and multiphase flow. EMT’s acoustic sand probe measures particle impact in real time to protect against erosion.
What Is a Sand Probe?
A sand probe is a dedicated monitoring device installed on oil and gas pipelines to detect sand production in real time. EMT’s Sand Probe uses a sealed piezoelectric acoustic sensor to capture the high-frequency signals generated when sand particles strike the pipe wall or the probe tip.
The probe inserts through a welded nipple or flange and sits inside the flow stream. It converts acoustic emission into a sand rate signal for flow-assurance and erosion management. Operators use it on wet-gas, oil, and multiphase lines where sand erosion threatens valves, bends, and meters.
Why Does Sand Erosion Matter?
Q: What happens if sand goes undetected?
A: Sand erodes elbows, chokes, and meters. Unchecked, it causes leaks, shutdown, and lost production.
Q: Can I measure sand without stopping the line?
A: Yes. EMT’s retractable sand probe retrieves and re-inserts under pressure through an isolation valve. No shutdown is needed.

FAQ
Q: What does a sand probe measure?
A: It measures sand production rate by detecting acoustic emission from particle impacts, giving real-time erosion data.
Q: Can it work in sour (H2S) service?
A: Yes. The 316L body and seals meet NACE MR0175 / ISO 15156 for sour environments.
Q: Do I need to stop the line to install it?
A: No. The retractable design inserts and retrieves through an isolation valve under full pressure.
Q: What output does it provide?
A: Standard 4–20 mA with HART, plus RS485 / Modbus on request for DCS or SCADA.
