Model P8
Continuous in-line measurement for 8″ process pipelines
8″ Pipeline Sensor for Brix, Total Solids & Density Measurement
Continuous in-line concentration measurement directly in 8″ process pipelines. The sensor measures total solids content — including both dissolved and suspended components — delivering stable, real-time data under high-capacity flow conditions without bypass loops or sample extraction.
Designed for major industrial operations including large sugar mills, high-volume food & beverage facilities, industrial dairy plants, and chemical processing where robust measurement and coating resistance are essential for large-scale continuous production control.

What is the Inmec Model P8?
The Model P8 is a digital microwave sensor for continuous Brix, total solids and density measurement in 8″ process pipelines. It measures the flowing product directly in the line, without bypass loops or sample extraction.
Where is the Model P8 used?
In sugar mills the Model P8 is used in primary evaporator circulation loops, main crystallizer circulation lines, high-capacity syrup mains and liquor transfer pipelines. It is also used in major food and beverage transfer and concentrate lines, main milk reception and whey processing mains, and chemical circulation loops and reactor systems.
Does the Model P8 measure suspended solids as well as dissolved solids?
Yes. The Model P8 measures total solids, both dissolved and suspended, across the flowing product. This suits opaque, viscous and coating-prone streams and slurries, where optical sensors that measure only dissolved solids at a prism surface struggle.
Does coating or buildup affect the Model P8 measurement?
No. The digital microwave measurement extends into the product volume, so the signal stays stable when coating or buildup on the sensor surface is part of normal operation.
Which Inmec pipeline sensor size should I choose?
Choose the model that matches the pipe size: the P2 fits 2″ (DN50), the P4 4″ (DN100), the P6 6″ (DN150), the P8 8″ (DN200) and the P10 10″ (DN250) industrial process pipelines, all with a flanged fitting. For sanitary lines of 1.5–3″ (DN40–DN80) with a Tri-Clamp connection, use the Model P-TC, and for tanks and vessels the Model IL. All use the same digital microwave measurement.
How is the Model P8 installed?
The Model P8 installs directly in a 8″ (DN200) pipeline with a flanged process fitting. The pipe must run full, and a process pressure of at least 1.5 bar is recommended to avoid free air at the sensor.
Does the Model P8 need a separate transmitter?
No. All signal processing takes place in the sensor itself. It provides 4–20 mA outputs for total solids and temperature, active and isolated, with a maximum load of 750 Ω, directly to the PLC or DCS.
What are the measurement range and accuracy of the Model P8?
The measurement range is 0–95 % Brix or total solids, factory configured to the customer’s specific total solids or density range. Accuracy and repeatability are ±0.01 % concentration, sensitivity is ±0.001 % and measuring resolution is 0.01 %.
What process conditions does the Model P8 handle?
The Model P8 operates at pH 3–14 and 0–140 °C, with an AISI 316L sensor body. A process pressure of at least 1.5 bar is recommended to avoid free air at the sensor.
What warranty does the Model P8 have?
The Model P8 comes with a 3-year warranty, reflecting its long-term stability in continuous industrial operation.
