Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 3 Daniel ® Valves In Load Rack Duty TURBINE METER THEORY The basic theory behind Daniel’s electronic liquid turbine meters is relatively simple. Fluid flow through the meter impinges upon the turbine blades which are free to rotate about...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 4 PATENTED* FLOATING ROTOR Flowing fluid enters the turbine through the forward suspension. When it encounters the sharp angle of the cone, the stream is deflected outward, increasing in velocity and causing a slight static pressure drop...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 5 Surge And Pressure Relief Valves MAGNETIC PICKOFF OF ROTOR VELOCITY The angular velocity of the turbine rotor is taken through the turbine meter wall by means of a magnetic pickoff. The stainless steel meter body is non-magnetic and of...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 6 TURBINE METER ROTOR AND BEARING DESIGN The primary differences in turbine meter technology are in the design of the rotor and bearings. The rotor is an assembly of up to twelve (in some designs this number is greater) blades locked int...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 7 RIMMED ROTORS FOR HIGHER RESOLUTION In the larger diameter Daniel Series 1500 Liquid Turbine Flow Meter (normally above 6” in line size), the resolution provided by a blade-type motor may be improved by the use of a rimmed (or shrouded...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 8 DANIEL ® SERIES 1200 LIQUID TURBINE FLOW METER Daniel Series 1200 Liquid Turbine Flow Meters are designed specifically for load rack service where a vital characteristic is repeatability. The meter deploys a lightweight rotor which is ...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 11 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...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 12 The deployment of this high resolution rotor in each of the sizes available gives a nominal K-factor twice that of the standard meter and allows for proving with a smaller size prover. The rimmed design is available as an option on 3”...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 14 RANGEABILITY OF LIQUID TURBINE FLOW METERS The flow ranges indicated in the previous tables show a nominal flow range -- with a turndown of 10:1 - at which the turbine will report measurement repeatable to the indicated specification ...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 16 METER PERFORMANCE IN HIGH VISCOSITY LIQUIDS Increases in viscosity of the measured liquid will reduce the rangeability of the flow meter. Generally, the minimum flow rate of the meter will have to be increased to maintain the linearit...

Technical Guide DAN-LIQ-Turbine Meter-TG-0807 August 2007 Page 17 INSTALLATION AND OPERATING RECOMMENDATIONS For a turbine meter to perform without increased uncertainty and in a repeatable and accurate manner, the flowing stream must be free of rotational components. The internal assembly supports ...
