OVAL Flowmeter/Mechanical Counter

General

High accuracy positive displacement flowmeter for wide range of fluids including water, petroleum, solvent. The mechanical counter allows checking of total flowrates in the field. Output furnished flowmeter is also available optionally.

Features

• 

High accuracy: ±0.5% RD (Option: ±0.2% RD)

• 

Metering chamber is of a pocketless configuration and is applicable to a wide range of liquids including chemical liquids.

• 

Low pressure loss, high durability
