Overwiew
The SMART 40M has been developed as a versatile low-cost solution for simple oil in water monitoring applications. Originally designed for use onboard vessels under MARPOL regulation the monitor has been re-developed for industrial use with user adjustable alarm points to suit the environmental requirement.
The monitor is designed with 2 key components, the control module and the calibrated measuring cell, allowing for easy recalibration and service of the device while retaining the data storage for historical data integrity.
The measuring cell comes as standard with a manual cleaning device for simple routine maintenance to ensure the optical cell is not fouling and maintains accuracy. Alternatively, this can be upgraded to a pneumatic autoclean which will ensure the cell is cleaned at regular intervals without need for manual cleaning.
The SMART 40M can also be offered as a Exd system for applications that require the monitor to operate in hazardous areas.
Applications
