SAFETY INFORMATION Before beginning installation works you must to read this document and follow its instructions The meter is powered from the battery (3.6 V), risk factors during the meter installation and service 0 fluid flowing within flow sensor with inner pressure up to 1,6 MPa and temperature up to 194 F. Only qualified technical personnel may install and maintain water meters. Personnel must be familiar with appropriate technical documentation and general safety instructions.

2 TECHNICAL DATA Ratio of the permanent flow rate to the lower limit of the flow-rate (selectable by the user): Q3/Q1 250 , Q3/Q1 315, Q3/Q1 400, Q3/Q1 800 The technical data of the meter are provided in Table 1.1. 1.1.
Maximum admissible working pressure (Pressure class) Flow profile sensitivity class Volume measurement unit’s Resolution of a displaying device Displaying range 16 bar (MAP16) U0 D0 GAL 1 GAL 999999999 GAL Display (LCD) The device is equipped with 2- lines LCD (Liquid Crystal Display): Upper line - 9-digits for displaying measured volume of water: Readings in normal mode: GAL. Lower line - 5-digits for displaying current flow rate, GPM, and special symbols for displaying operation modes.
The interfaces are intended for data reading and meter parametrisation. The meter is configured for being powered only from the internal battery, and the time of communication through the additional interfaces is automatically limited to save the battery – up to 20 minutes per month. Unused communication limit is summed up. If the limit is expired, the interface is blocked and the new time limit of communications will start only after the change of the hour (16 seconds for each next hour).
and dynamic range, temperature class, where it differs from T30, maximum admissible working pressure (MAP), pressure loss class; installation sensitivity class of the meter, latest date by wich the meter shall be replaced, software version number, IP code. The following is indicated on the housing of meter: – the type of connection (thread or relative diameter); – the flow direction. Sealing The meter casing is imperceptibly closed. Any unautorized opening of the housing is impossible without damaging.
It is recommended to select meter installation place as far as possible from potential sources of vibration (for example, pumps). The gaskets must match with the pipe diameter. During the installation gasket must be exactly centered with the center of the pipe cross-section to avoid sticking out gaskets inside the pipe. Checking of installation and parameter setting If the meter is installed correctly, when there is flow, the display of the meter should display flow readings.
Special symbols: Symbol Description Leakage Radio transmitter is active Pipeline is empty Pipe is cracked (Burst) Fault (error) Battery replacement time The symbol is shown when there is a significant meter operation error. For the Info code, see the LCD menu item 1.7 (Paragraph „Menu structure“). Menu structure Menu structure in normal mode is presented in Fig. 6.1. Meter menu items are switches automatically.
Viewing the readings in normal mode (User menu) Remark: Here the full list of shown parameters is represented. For the specific meter it can be reduced ID 1.1 Parameter Total volume, Flow rate Value (example) Remarks GAL GPM 1.2 Forward flow volume 1.3 Informational volume flowing in reverse direction 1.4 Water temperature value 1.5 Date 1.6 Real - time 1.7 Info code and error occurrence date 1.8 Accumulated volume on set day /date 1.
1.10 User identification number 1.11 Control number The indication of irrelevant parameters can be turned off. Also, parameters that are not relevant to the set meter configuration will not be indicated. The indication of parameters can be turned on or off by means of the configuration programme „W1 TOOL“ through the optical interface when installing the meter (if the meter is in the transport mode).
8 - Low battery (less than 12 months lifetime left) 0 - Normal operation 4 - Hardware failure detected 8 - Hardware failure detected 0 - Normal operation 1 - No signal; the flow sensor is not filled with water XXnX XXXn 2 - Reverse flow 4 - Flow rate is greater than 1,25∙Maximum flow (indicated q =1,25∙Maximum flow) 8 - Freeze alert Active info codes are added, if it is detected more than one error.
7 TRANSPORTATION AND STORAGE REQUIREMENTS Packed meters may be transported in any type of covered vehicle. Equipment should be anchored reliably to avoid shock and possibility to shift inside vehicle. Meters should be protected against mechanical damage and shock. No aggressive chemical substances should be stored together because of corrosion hazard. Storage and transportation temperature: -13°F...158 °F (drained flow part) Humidity: not more than 93%.
