VLF (very low flow) flowmeters have been designed to measure the flow of light fuel or diesel oil, for example, in applications such as measuring fuel oil consumption at large boiler plants, in a diesel engine generator and on engine test rigs.The register unit is housed in a vacuum sealed casing secure from dirt, dust and condensation. Operation of the meter can be verified by checking the disc rotation in the dial center.

Features

Model	VLF-4	VLF-8	VLF-20
Size	1/8″	3/8″	3/4″
Min. Flow (Qmin)	.25 gph	1 gph	8 gph
Max. Flow (Qmax)	20 gph	50 gph	390 gph
Continuous Flow (Qcont)	14 gph	35 gph	265 gph
Max. Pressure	355 psi	355 psi	225 psi/td>
Max. Temp	140° F	140° F	260° F

Because of the value and volume of product metered in any bulk plant or truck operation, errors are costly. For this reason, accuracy is the most important criteria in flowmeter selection. Neptune 1-1/4″ and 1-1/2″ Type 40 flowmeters provide the accuracy and convenience you need in measuring refined petroleum products and allow you to control cost, loss prevention and invoicing.

These rugged positive displacement flowmeters incorporate the Neptune refined fuel measuring chamber, which has only one moving part…the oscillating piston.

The New York City Transit Authority employs 1-1/2″ Type 40 Petroleum meters on dispenser stations for bulk refueling of city buses.

Features

• Outstanding long-term accuracy
• Reliable – the oscillating piston is the only moving part in the meter
• Easy Installation
• Fast and easy calibration positive change gear selection
• Low cost of maintenance and cleaning
• Ideal for loss control, loss prevention and invoicing
• Weights and Measures approved world wide
