A monitoring system for monitoring fluid parameters in a lubrication system of an engine may include an input conduit configured to be in fluid communication with the lubrication system at a first location upstream of an oil cooler of the lubrication system. A monitoring device may be in fluid communication with the input conduit. An output conduit may be in fluid communication with the lubrication system at a second location downstream of the oil cooler. The output conduit may include a flow restrictor configured to provide a desired pressure and flow of a fluid to the monitoring device via the input conduit.
