Application Flexibility

Commonly metered liquids range from non-conductivelow viscosity solvents to extremely viscous lubricants,chemicals and food bases.Application flexibility is further enhanced as meter per-formance is independent of flow profile eliminating theneed for straight pipe runs required with most othermetering technologies.Multipulse has no stagnate chambers to harbor contami-nants. There are no restrictions on mounting orientationand the flowmeter may be operated under vacuum flow,pumped flow or gravity flow conditions.

Design Simplicity

The simple and robust design of the INVALCO PD Flow-meter offers the advantage of only one moving part withboth high resolution open collector and reed switch out-put as standard.As each piston rotation passes a known liquid volume,the inherent repeatability of the multipulse positive dis-placement flowmeter makes it particularly suited tobatching and dispensing duties.
