Your Benefits
- Reliable monitoring and flexible control of the system without additional transducers
- Simplifying burner settings for optimum performance
- Simple commissioning, maintenance-free
- Space saving installation without requirement for straight inlet or outlet paths
- Easy to install without restriction either horizontally or vertically
- Maximum safety due to integral particle filter in meter inlet
Meters for heavy fuel oil should have a nominal diameter of DN 20 or larger
All threaded meters from 1/2"DN15, to 1.5"DN40 are supplied complete with BSP or NPT threaded Brass Adaptors, which enable the meter to be removed easily should it require inspection / testing. These fittings also enable the meter to be orientated in the desired plane. These fittings are not available for 2"DN50 Meters. Fittings shown below;
IMPORTANT - All meters must be fitted with a pre-filter of 100 Microns, Maximum. Ingress of particles over 100 microns may lead to wear and or jamming of the Rotary Piston, and will not be covered by Warranty. Oilybits can supply Inline Brass Y-Strainers with a cage supported 100 Micron Stainless Steel Mesh cloth, prices at foot of lising.
