Omnitek S-Flow Automatic Houillon Viscometry System S-Flow 3500 Fully Automatic Dual Bath, Integrated Viscosity Index

Description

Test Method

The kinematic viscosity characterizes flow behavior. This method covers the measurement of kinematic viscosity of transparent and opaque liquids, such as base oils, formulated oils, diesel oil, biodiesel blends, residual fuel oils, marine fuels, and used lubricating oils using an automated Houillon viscometer.

Features

Applicable for fuels, base oils, formulated oils, and petroleum products as well as water-based fluids

Compliant with requirements for ASTM D7279, ASTM D2240, and correlation to ASTM D445

High throughput: up to 80 samples per hour per bath under ideal operating conditions

Description

The Omnitek S-flow range of instruments consists of compact, bench-top automated viscometry systems for the analysis of used and new lubricants. It is also the ideal system for used oil analysis laboratories that need to test a wide range of lubricant viscosities. Additionally, S-flow systems are used for analysis of fuels like diesel, bunker fuel and biofuel (feedstock), hydraulic and metal working fluids and even gelatins and inks.

The S-flow system is a self-contained viscometer system that consists of a thermostatic bath with circular heater and a control touchscreen. The bath contains 4 viscometer tubes together with optical sensors to detect the flow of oil through the tubes. All measuring tubes function independently of each other.

The system contains a touchscreen with storage up to 10,000 measurement results. The touchscreen allows the user to control and operate the system. Although a PC is not required to operate the instrument, additional software is available for LIMS connection and full data storage and reporting. The user has the option to operate in two modes, standard viscosity determination or tube calibration. In both modes, the operator chooses how many determinations must be made for an average result. Additional parameters such as tube constants and cleaning cycle are also controlled by the operator.

Because the sample volume is very low (0.3 - 1 mL), the entire measurement cycle is very short. After the user injects the sample into the tube, the sample travels down towards the optical sensors and heats up to the test temperature very quickly. Upon reaching the first sensor, the time measurement is started. When the second sensor is reached, the measurement is stopped, and the result is displayed on the touchscreen or through the PC software. Then, a predefined cleaning cycle automatically commences, cleaning and drying the tubes completely.

The entire cycle time ranges between 3 - 10 minutes per tube, allowing a throughput of up to 80 tests per hour per bath under ideal operation conditions. After the injection of the sample, operator presence is no longer required. The operator only needs to return after the system has completed the measurement and cleaned the tube.
