The Actaris (formerly Schlumberger) Neptune Type S and Type MP meters for
oil, chemical, and general service is one of our standard offerings for bulk unloading and custody transfer
In general we offer these meters for any oil being pumped at a high rate or where a
resettable or batching type meter is required. The Type S is only available
in bronze, while the Type MP is available in bronze, cast iron, or
stainless steel. Both non-resettable and resettable registers are available
with various pulser options. The MP meter is now available with a digital
display and pulse/4-20 madc outputs.
A mechanical batching system consists of a flowmeter with a large,
register mounted on top with a control valve bolted to the discharge
side of the
meter. A linkage arm between the register and the valve controls
operation. The operating steps are (1) reset the register to zero,
(2) set the
desired batch volume, and (3) pull the handle opening the valve
to start the flow.
The register will close the valve automatically when the preset
volume has passed.
This type of meter is available in a single or two-stage shut off.
We have two
manufacturers that offer this type of batching system.
• Simple, one piece installation
• Change gears are available for field calibration
• Best option for explosion proof applications if meter design
• Limited to larger flowmeters capable of producing enough torque
to drive the register
