MASS FLOW METER

BULK OFF-LOADING
The Schlumberger mass flowmeter can control off-loading and inventory management of costly liquids with outstanding accuracy year-round. 
CONTAINER FILLING
Containers can be filled precisely with single or multiple fluids. 
SINGLE LIQUID/SINGLE TANK
Delivery of a single costly fluid, such as a catalyst, can be metered with custody-transfer precision. 
MULTI-LIQUID/MULTI-BATCH
Delivery of multiple costly or critical quantities for multiple formulations can be managed by a single mass flowmeter.
