ART 26 + 27 DZR Commissioning Set Flow Data and Installation Instructions Issue 1 This data sheet is designed as a guide and should not be regarded as wholly accurate in every detail. We reserve the right to amend the specification of any product without notice ART 27 Technical Data 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. Flow Coefficient The flow rate can be calculated using the Kv value and a measured signal. Kvs = Q*36 Kv = 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”UUL ½”UL ½”L ½”M Kvs 0.103 0.234 0.473 0.976 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.

We reserve the right to amend the specification of any product without notice ART 26 + 27 Technical Data 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. 5D 2D 5D 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) Issue 1 This data sheet is designed as a guide and should not be regarded as wholly accurate in every detail.
