DANIEL® SERIES 1500 LIQUID TURBINE FLOW METER

The Daniel Series 1500 Liquid Turbine Flow Meter is designed for applications requiring rugged dependability with high accuracy and throughput. Used on pipelines, marine loading and other demanding systems, the internals used are well proven in the Daniel PT meter. The Daniel Series 1500 Liquid Turbine Flow Meter utilizes these internals in a body designed to accept a Universal Mounting Box (UMB) and the latest pickoff and pre-amplifier technology.

With upstream and downstream self-centering hangers, highly durable rotor assembly utilizing tungsten carbide sleeve and journal bearings, and a floating rotor design, the Daniel Series 1500 Liquid Turbine Flow Meter is suited to those applications where downtime is unacceptable.

In such applications, dual pulse transmission is normally used to allow the meter instrumentation (normally a flow computer) to check the fidelity of pulse transmission. The single UMB housing contains 1 or 2 pickoffs and a dual channel preamplifier. When configured with 2 pickoffs the square wave outputs are 90º electrically out of phase.

The Daniel Series 1500 Liquid Turbine Flow Meter (2” and up) is available with a second UMB as an option. For meters 3” and above in this configuration, it is thus possible to have up to 4 matched pulse outputs. Corresponding pairs are then 90º electrically out of phase.

The Daniel Series 1500 Liquid Turbine Flow Meter utilizes only tungsten carbide journal bearings. In applications with fluids of adequate lubricity, a film of the measured fluid lubricates the journal which contributes to the enormous longevity of this design. These bearings are extremely hard (Rockwell A-94) and are polished with diamond paste to a smoothness of two micro-inches (a mirror finish).

The rotor may be blade-type or rimmed-type. Rimmed (or shrouded) rotors have the advantages of greater structural strength and the possibility of higher resolution, as a greater number of paramagnetic buttons than of blades may be used on the stainless steel rim. A bladed rotor is limited to 1 pulse per blade per revolution, with the practical limit for the blades being 12. With a rim, or shroud, there may be up to 64 pulses (buttons) per rotor revolution.

The high resolution (HR) rotor option for the Series 1500 rotor is available in 6” through 16” sizes. In this design the rotor rim is a slotted 400 series stainless steel, designed with twice as many slots in the HR rotor as buttons on the standard rotor.
