Phosphate Ester Flow Rate Meters

Compatible with aviation lubricants such as Skydrol®, as well as fire-retardant fluids such as Pydraul®, Fyrquel® and Houghton 900® series.

Choice of three materials construction: Select from aluminum, brass or stainless steel to meet system and media compatibility requirements.
Unrestricted mounting: Allows the designer to install the meter in any orientation – horizontal, vertical or inverted.
Multi-user: Factory calibrated for phosphate esters, these versatile meters can be used to verify hydraulic power unit outputs, as well as test machinery and tools for proper fluid flow rates.
Rugged & reliable: These meters are constructed with all metal pressure vessels, allowing safe, permanent installation in industrial systems.
High pressure opertion: The magnetically coupled follower design allows operation to 6000 PSIG.
24 different ports available: Standard selection of NPT, SAE and BSP ports reduces the amount of adapters required for installation.
Low cost accuracy: ±2.5% of range accuracy in center third of scale; ±4% in upper and lower thirds.
Bi-directional & reverse flow option offered:

Engineering specifications:

The Phospate ester in-line flow rate shall:

• Include a direct-reading scale corrected for phosphate ester media
• Use the variable annular orifice technique with compression spring recoil
• Not require inlet or outlet straight plumbing, or require vertical pipe mounting
• Have a measuring accuracy of ±2.5% of full scale in the center third of the measuring range, and ±4% in upper and lower thirds
• Have a stainless steel sharp-edged orifice
