2 Descriptive Annex 1 INTRODUCTION This pattern of a liquid measuring instrument is for measuring the volume of cold water which has passed through it. It is a concentric, semi-positive displacement cold-water meter having a Q 3 (permanent flowrate) of 1.6m 3 /h and a Q 3 /Q 1 turndown ratio of 315 (R315) or a Q 3 (permanent flowrate) of 2.5m 3 /h and a Q 3 /Q 1 turndown ratio of 400. It is not designed to measure reverse flow. The meter is shown in Figure 1 2 FUNCTIONAL DESCRIPTION It incorporates a semi-positive displacement rotary piston measuring assembly mounted in a plastic body that is fitted into a thermoplastic injection moulded body for connection to a manifold in any orientation. The rotary piston drives a magnet that couples to a non-resettable totalising display (register) that indicates up to m 3. The register is positioned on the top of the measurement chamber and secured between the plastic snap-shut register cover and meter body. The connection to the manifold is arranged via a British Pipe Thread G1½"A male threaded co-axial inlet/outlet at the base of the meter body. A cross section diagram is shown in Figure 2. 3 TECHNICAL DATA 3.1 Flow designation Meter with Q 3 = 1.6 m 3 /h Table 1 Related flowrates according to each Q 3 /Q 1 designation Q 3 /Q 1 (R) Q 2 /Q Q 1 Minimum flowrate (m 3 /h) Q 2 Transitional flowrate (m 3 /h) Q 3 Permanent flowrate (m 3 /h) Q 4 Overload flowrate (m 3 /h) Meter with Q 3 = 2.5 m 3 /h Table 2 Related flowrates according to each Q 3 /Q 1 designation Q 3 /Q 1 (R) Q 2 /Q Q 1 Minimum flowrate (m 3 /h) Q 2 Transitional flowrate (m 3 /h) Q 3 Permanent flowrate (m 3 /h) Q 4 Overload flowrate (m 3 /h)

The transmission of measurement data using this device is not covered by this approval. This device has three variations; one powered by A cell batteries, the second powered by AA cell batteries and a third powered by Tadiran Lithium Batteries. 3

4 5 APPROVAL CONDITIONS The certificate is issued subject to the following conditions: 5.1 Legends and inscriptions The instrument bears the following legends: CE marking Supplementary metrology marking Notified body identification number Permanent flow rate Q 3 Flowrate range Q 3 /Q 1 (R) Serial number Manufacturers mark or name Certificate number 6 LOCATION OF SEALS AND VERIFICATION MARKS 6.1 Securing method The measuring assembly is secured by locating the snap fit plastic cover to the meter body. The register is positioned between the plastic cover and the meter body. The plastic cover and meter body have integrally moulded clips and once fitted, unauthorised dismantling is not possible without leaving evidence of tampering. 6.2 Location of verification markings The verification markings identified in 5.1 are permanently etched on the top surface of the shroud. 7 AUTHORISED ALTERNATIVES 7.1 Electronic Register CZ-4000 Having an electronic register model CZ-4000 as described in Evaluation Certificate GB
