Chemical Boiler Oil Content Monitor – Condensate Return Line Solution
Ensuring the purity of condensate recirculated to a boiler is critical for plant reliability and operating cost. Our chemical boiler oil content monitor condensate return line provides continuous, real‑time oil‑in‑water detection directly within the return piping, enabling proactive maintenance and compliance with environmental standards.
Designed for high‑temperature, high‑pressure steam systems, the sensor integrates seamlessly into existing pipelines without interrupting flow. The unit delivers alarm set‑points, trend logging, and remote diagnostics, helping procurement engineers eliminate costly fouling and unplanned shutdowns.
How It Works – Inline Oil‑In‑Water Detection
The monitor employs a dual‑wavelength infrared sensor positioned inside a stainless‑steel housing that fits directly onto the condensate return line. As condensate flows past the probe, the sensor measures the absorbance at wavelengths specific to hydrocarbon molecules, converting the signal into an oil concentration percentage.
Data is transmitted via Modbus‑TCP or 4‑20 mA to your DCS/SCADA system. When the oil content exceeds the predefined threshold, an audible and visual alarm activates, and the event is logged for trend analysis. The device is calibrated in the field and can be re‑calibrated without disassembly, minimizing downtime.

Application Scenarios
- Large‑scale power generation where condensate is recycled to improve boiler efficiency.
- Industrial process heating (refineries, petrochemical complexes) requiring strict oil‑in‑water limits to protect turbine blades.
- District heating networks where water quality impacts system lifespan and regulatory compliance.
- OEM integration for custom boiler packages that demand inline oil monitoring as a standard feature.
By placing the monitor directly on the condensate return line, operators gain immediate visibility of oil ingress caused by seal wear, lubricant leaks, or pump failures, enabling corrective action before damage propagates.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for the monitor?
We accept orders as low as a single unit for prototype evaluation; bulk pricing tiers begin at 10 pieces.
Can the sensor be customized for higher pressure applications?
Yes. Our engineering team can upgrade the housing to a 10 bar rating and select alternative sealing materials upon request.
What is the typical lead time?
Standard configurations ship within 15–45 days after order confirmation, depending on order volume and any optional customizations.
Is there a warranty or service agreement?
All units come with a 24‑month limited warranty covering manufacturing defects. Extended service contracts are available for on‑site calibration and software updates.
