DANIEL™ SERIES 1500 TURBINE METER OCT 2013
INSTALLATION 3-5
C. Flow Conditioning Plate
The flow conditioning plate is available for all standard Series 1500 Turbine meters, sizes 3" - 8"
and is designed to eliminate product flow characteristics such as liquid swirl and non-uniform
velocity profiles (induced by piping configurations and other elements of the system) that may
impede proper measurement within the turbine meter run. The plate is installed directly into the inlet
of the meter. Due to the flow conditioning influence on the incoming product, this reduces the
requirement for upstream flow straightening piping. It is recommended that a minimum of five pipe
diameters be maintained upstream and downstream of the meter to assure proper operation. Actual
length will be determined by piping requirements specific to the application.
D. Strainers
A strainer of proper size should be installed upstream of the meter to protect it from the introduction
of foreign material which might damage the meter. Recommended mesh sizes include: 40 mesh for
refined products, and 10 to 20 mesh for crude products (depending on the product being measured).
Strainer Monitoring:
1. Recommended procedures dictate that regular, scheduled cleaning of the strainer basket be
conducted to prevent filling and rupturing of the screen.
2. Pressure gauges installed on both sides of the strainer will indicate differential pressure
across the strainer. High pressure differential caused by filling of the basket or occlusion of
foreign material can cause strainer basket rupture resulting in possible meter damage.
