Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software.

For improved consistency of results, two digital indicating mass flow controllers are used for precisely measuring and controlling sstm amount of air delivered to the air diffuser. Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton.

The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. Seta Autowash Part Number The Autowash is a bench top unit which automatically cleans and dries Mott and Norton diffusers using one or two solvents without removing the air tube. Specifications subject to change without notice.


A multi-pane insulated window allows full view of the test cylinder for observation of the foam. Click for Software Screen. Caution should be taken when handling mercury and mercury containing products. Use of silicone oils is not recommended since only a few parts per million contamination will distort the foam results. Silicone fluids are not recommended. Conventional bath fluids darken and require frequent replacement.

Also provided is a digital display time counter showing remaining seconds to the next even requiring operator attention. Once you start a programme you can leave the Autowash unattended and the instrument sounds an audible warning when the cycle has finished.

Especially in high-speed gearing and high-volume pumping systems, the tendency of oils to foam can lead to inadequate lubrication or cavitation which may result in mechanical failure.

Even low levels 1 ppm and above of silicone contamination interfere with test results. Model 24 dual foam test bath is the traditional arrangement with two glass jars d8992 on a supporting base.

Means of empirically rating the foaming tendency and the stability of the foam are described.

Foaming Characteristics of Lubricating Oils – ASTM D892, D6082

Two channel totalizer installed in Model baths. An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available. Air drying tower with Dririte desiccant and stand. Flow cooler used with Model 24 and 28 liquid baths.


Two channel digital flow control unit, upgrade from rotameter incl. Replaces silicones as heated bath medium.

Flat bottomed glass mL graduated test cylinder starting at 10mL and continuing at 10mL increments. A touch screen allows the operator selection and full adjustment asmt all test parameters.

The Lawler proprietary Windows software manages the testing operation and all the data. Replaces silicones as heated bath medium. Copyright Stanhope—Seta Limited This is calculated by the software program.

Test assembly includes d8992 of each: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Novel, sophisticated heating system and control allows the sample to reach test temperature in less than the 60 minutes specified by the method. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure.

Available as a stand alone model or incorporated into any of the foam testing baths.
