Widely preferred for their low-cost of installation, maintenance and ownership, Daniel liquid turbine flow meters offer high accuracy and repeatable measurement under the most demanding conditions of custody transfer applications. Typical installations include crude oil and refined product pipelines, marketing terminals, tank farms as well as mobile operations.

Highly accurate measurement is achieved by using a bladed rotor that turns at a speed proportional to rate of flow. The rotation of the rotor is sensed by electrical pickoffs mounted on the meter body, generating a pulsing voltage. The total number of pulses collected over a period of time represents the metered volume.
