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-amplier
technology.
With upstream and downstream self-centering hangers, highly durable rotor assembly utilizing tungsten carbide
sleeve and journal bearings, and a oating 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 ow
computer) to check the delity of pulse transmission. The single UMB housing contains 1 or 2 pickoffs and a dual
channel preamplier. When congured 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 conguration, 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 uids of adequate lubricity, a lm of the measured uid 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 nish).
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.
