Model IL-G
Sanitary tank and vessel sensor with a flush-mounted GEA Varivent connection. CIP-compatible, for syrup, beverage and dairy tanks.
Sanitary Tank and Vessel Sensor for Brix, Total Solids & Density Measurement
The Inmec Model IL-G is a digital microwave sensor for continuous Brix, total solids and density measurement in sanitary tanks and vessels. It mounts flush in the tank wall with a GEA Varivent weld-in connection, uses a sanitary EPDM gasket and an AISI 316L sensor body, and is CIP compatible. Because it measures total solids by digital microwave rather than optically, it gives stable, real-time readings in opaque, viscous and coating-prone products such as syrups, beverage concentrates and dairy mixes, without bypass loops or sample extraction.

Installs flush in the tank or vessel wall with a GEA Varivent weld-in part: Type T / T-S (flush from the inside) or Type U / U-S (front-flush). The sensor connects with a GEA Type N flange and hinged clamp. No bypass or recirculation loop required.
Control the process where it happens — inside the tank, in real time.
IL-G Installation Options for Sanitary Tanks
The Model IL-G mounts flush in the tank or vessel wall with a GEA Varivent weld-in part. Four Varivent types cover flat walls, curved walls and eccentric positions.
| Varivent type | Mounting | Best for |
|---|---|---|
| Type T | Flush with the tank wall from the inside | Flat installation orientation (conical inner contour) |
| Type T-S | Flush with the tank wall from the inside | Eccentric positions (cylindrical shape) |
| Type U | Front-flush in the tank wall | Flat installation orientation (conical inner contour) |
| Type U-S | Front-flush in the tank wall | Adjusting to inner tank contours (cylindrical shape) |
All versions: measurement range 0–99 % Brix / total solids, repeatability ±0.01 % concentration, GEA Type N sensor flange with hinged clamp, sanitary EPDM gasket, AISI 316L sensor body and weld ring, CIP compatible, process temperature 0–140 °C, pH 3–14, max pressure PN10, 2 × 4–20 mA output (Brix / TS % and temperature), automatic temperature compensation.
How to Choose a Sanitary Brix Sensor for Tanks and Vessels
Food, beverage and dairy plants usually compare in-tank Brix sensors on six points:
- Tank or pipeline – measure in the tank for batching, blending, standardisation and batch correction. For continuous flow in sanitary lines, the Model P-TC is the pipeline equivalent.
- Hygienic connection – a flush-mounted connection leaves no pocket for product to collect. IL-G uses the GEA Varivent system, widely used in dairy and beverage plants.
- CIP resistance – the sensor must withstand cleaning cycles without drift. IL-G is CIP compatible with a 316L body, EPDM gasket and 0–140 °C process range.
- What is measured – optical refractometers measure dissolved solids at a prism surface, which works well in clear liquids. Digital microwave sensors such as IL-G measure total solids, both dissolved and suspended, in the product volume, which suits opaque, viscous or coating-prone products.
- Product conductivity – digital microwave measurement is suited to products up to 13 mS/cm. Highly mineralised products should be checked before selection.
- Control integration – continuous 4–20 mA Brix and temperature signals to the PLC or DCS enable automatic dosing, dilution and batch correction.

Which Inmec sensor is designed for sanitary tanks and vessels?
The Model IL-G is Inmec’s sanitary tank sensor. It mounts flush in the tank wall with a GEA Varivent connection, uses a sanitary EPDM gasket and an AISI 316L body, and is CIP compatible.
How is the IL-G installed?
A GEA Varivent weld-in part is welded into the tank or vessel wall: Type T or T-S (flush from the inside) or Type U or U-S (front-flush). The sensor connects with a GEA Type N flange and hinged clamp. No bypass or recirculation loop is needed.
Is the IL-G CIP-compatible?
Yes. The IL-G is CIP compatible, with an AISI 316L sensor body, sanitary EPDM gasket and a process temperature range of 0–140 °C. Its digital microwave measurement keeps a stable signal through cleaning cycles and normal product coating.
Does the IL-G measure Brix or total solids?
The IL-G can be configured to measure Brix (°Bx), total solids (%) or density (g/l), one at a time. The measurement range covers 0–99 % and is factory configured to the customer’s process range, with repeatability of ±0.01 % concentration.
Which applications is the IL-G used for?
Typical applications are syrup blending and storage tanks, beverage concentrate tanks, dairy and liquid food batching, batch correction and sugar dosing, as well as mixing tanks and reactor vessels in other process industries.
What is the difference between the IL-G and the P-TC?
The IL-G measures inside sanitary tanks and vessels with a flush Varivent connection. The P-TC measures in sanitary process pipelines with a 1.5″, 2″ or 3″ Tri-Clamp connection. Both use the same digital microwave measurement.
Are there process limits to check before selecting the IL-G?
Digital microwave measurement suits products up to 13 mS/cm conductivity, so highly mineralised products should be checked before selection. The IL-G operates at pH 3–14 and 0–140 °C. A tank pressure of at least 1.5 bar is recommended to avoid free air at the sensor, and the maximum pressure rating is PN10.
Does product coating affect the IL-G measurement?
No. The digital microwave signal extends into the product volume, so normal coating on the sensor surface does not affect the reading. Temperature compensation is automatic.
