Filter Flow Resistance Tester
Meet the standard:
ISO 3968
SAE J806
Product Introduction:
The Filter Flow Resistance Tester operates by circulating a test fluid (such as hydraulic oil, lubrication oil, fuel, water, or air, depending on the filter's intended application) through the filter element or complete filter assembly under test. A variable speed pump or flow control valve is used to establish and control a range of flow rates through the filter. Pressure sensors or transducers are strategically placed immediately upstream and downstream of the filter to measure the pressure on both sides. The difference between these two pressure readings is the pressure drop across the filter at that specific flow rate. The tester systematically measures the pressure drop at multiple flow rates across the filter's operating range.
The instrument is used for:
Determining the clean filter pressure drop versus flow rate characteristics of filter elements and assemblies.
Comparing the flow resistance of different filter designs, media, and manufacturers.
Selecting filters based on acceptable pressure drop limits for a given system flow rate.
Validating filter specifications provided by manufacturers.
Optimizing hydraulic or lubrication system design to minimize energy losses due to filtration.
Quality control during filter production to ensure consistent flow characteristics.
Research and development of new filter media and designs with lower flow resistance.
Product Advantages:
Provides objective, quantitative data on a filter's resistance to fluid flow when clean.
Essential for accurate filter selection and system design based on pressure drop limitations.
Helps optimize system energy efficiency by characterizing pressure losses across the filter.
Standard compliant test methods (ISO 3968 is a key standard) ensure comparable and reliable results.
Product Features:
Based on typical Filter Flow Resistance Testers:
Test fluid reservoir.
Variable flow rate pump or flow control system capable of generating and maintaining stable flow rates through the filter over a specified range.
Filter housing or fixture designed to securely hold the filter element or complete filter assembly under test, with connections for upstream and downstream pressure measurement.
Pressure transducers or sensors located upstream and downstream of the filter to measure pressures.
Differential pressure transducer (often included) to directly measure the pressure drop across the filter.
Flow meter to accurately measure the test fluid flow rate.
Temperature control system for the test fluid to ensure testing is performed at a consistent and relevant temperature, as viscosity affects pressure drop.
Main parameters:
1. System pressure gauge range: 30bar
2. Use of working medium: SAE5W engine oil
3. Pressure rise accuracy: 0.5bar/sub-increment point
4. Measuring temperature range: room temperature
5. Protective cover: transparent
