Technical Data
Flow Coefficient
The flow rate can be calculated using the Kvvalue and a measured signal.
Kv= Q*36 Kvs = Q*36
√∆P √∆Ps
where Kv&Kvs = flow coefficient (m3/hr at 1 bar differential)
Q = flow rate (l/s)
∆P = headloss attributable to valve (kPa)
∆Ps = differential pressure across tappings (signal) (kPa)
Kvs Values
Size ½” ¾” 1” 1¼” 1½” 2”
Kvs 1.8 4.1 7.5 16.6 23.0 47.4
Pressure Loss
The pressure loss across a metering station is less than signal differential pressure
indicated on the flow charts. The pressure loss is obtained by multiplying the
pressure signal by the pressure recovery factors given in the table.
This applies to when the metering station is used in a stand alone application or
close coupled to a double regulating valve.
Pressure Recovery Factors
The Albion ART 27 is a fixed orifice metering station used to measure the flow
passing through it, which can be used close coupled to an ART 26 double
regulating valve to form a commissioning set.

Technical Data
Sizing
Once the required flow rate has been calculated, the size of the metering station
can be determined based on the following:
The minimum signal at the design flow rate of 1 kPa.
For minimum pressure loss, a maximum signal of 4.7 kPa, which corresponds
to the maximum differential pressure range of a fluorocarbon manometer.
Pressure Equipment Directive
Under the Pressure Equipment Directive (PED) these metering stations and double
regulating valves have been specified for Group 2 Liquids i.e. non-hazardous
Sizes ½” to 2” are classified as SEP (Sound Engineering Practice)
5D 2D
Pressure Loss
The pressure losses for the ART 26 double regulating valves are given on the
individual flow charts along with the corresponding Kv values at the various
positions open.
Installation
Metering stations must always be installed with a minimum of 5 pipe diameters of
straight pipe, without intrusion, upstream of the metering station.
Downstream of the metering station a minimum of 2 pipe diameters of straight
pipe are required.
When close coupled to an Albion ART 26 double regulating valves only the
straight pipe upstream of the metering station is required.
