Description

Overview

GAOTek inline refractive index sensor is an inline digital refractometer that measures the refractive index of a liquid sample and provides a direct reading of highly accurate concentration values for a wide variety of water and process-related applications. It is a stand-alone device capable of self-sustained operation, live data display, and logging. inline refractive index sensor also offers fully integrated 4-20mA and RS-485 Modbus output signals for connectivity to any microprocessor-based controller, display, PLC, or DCS network. inline refractive index sensor has built-in temperature-dependent equations to convert the measured sample temperature and refractive index to the percentage concentration of Mono Ethylene Glycol (%MEG), Mono Propylene Glycol (%MPG), Sugar Content (%BRIX) and Advanced Low Viscosity Fluid (%ALV). Additional concentration curves may be added in the future by GAOTek as the market demands. Inline refractive index sensor is a very robust, digital sensor capable of operating in contaminated fluid samples. It is important however to note that users should take all precautions to mitigate and filter suspended solids from the sample stream before the sensor to avoid tenacious deposit build-up on the sensor eye. In highly fouled applications, GAOTek recommends that users conduct sensor eye cleaning regularly per the manual guidelines. GAOTek will be launching an automated sensor cleaning accessory for installation into the Tri-Clamp Flow Cell assembly as an optional accessory soon.
