Contact: Manager Liu: 13501196526 qq 2645674007 Website www.shuibiao100.com winter use the Xiaogan prepaid meter Note heavy snow brings us to the winter, the meter will be subject to the test of winter, if not pay attention to the protection of water meters in the winter, it is likely to cause unnecessary trouble. For the safety of your water meter and water facilities, prevent frozen to affect your production or life Here we give a brief introduction to winter use some of the considerations of the water meter. First, introduce the winter meter antifreeze knowledge a water pipes, water taps and other water facilities, preferably with cotton, linen, dry cloth plastic foam and dry warm mulch or dressing 2 night sure to turn off the kitchen, toilet, external as well as all the shady room windows, Make sure that the room temperature is above freezing. 3 in cold weather (-5 ° C or less) it is best to water at night after a little screw on the tap so that water flows into the line, and to ensure that water flow in the pipes to prevent cold and freezing at night. 4 proper storage to prevent frozen water meter affect normal life "Once the water meter, water pipes freezing, you should use a hot towel wrapped faucet, pouring warm water, the faucet thaw. And then hit the tap, along with warm water faucet slowly thaw water pipes. In this case, if the water table at still no water, then the water meter is frozen, then should then hot towel, with not more than 60 degrees warm water and poured on the water meter. Do not pouring boiling water, fire baking to prevent thermal expansion and contraction burst pipes, damage to water facilities. ◆ Main technical parameters Maximum allowable working pressure: less than equal 1Mpa the maximum allowable temperature: cold water vertical meter to 30 ° C, hot water vertical meter is 90 ℃ metrological characteristics: from minimum flow, including up to but excluding the lower zone of the transitional flow the maximum permissible error of ± 5%; from the transitional flow to the maximum flow in the maximum allowable error cold water vertical meter to ± 2%, hot water vertical water meter ± 3% DN15 to 25 RF card cold (hot) water vertical meter pulse signal 0.01m3, 0.1 m3, 1 m3 selected according to the situation 20 cold Dn15 and (hot) water vertical meter performance parameters and dimensions dual power base table, pure water-based the table orders In particular, description of specific parameters: Power supply: rechargeable lithium-ion battery 3.6V; static operating current: 5uA; 3, the normal operating current: ≤ 20uA; 4, a multi-card life:> 100 000 times; 5, the working environment: 0 ° C to 40 ° C (cold water); 0 ℃ ∽ 95 ° C (hot water), maximum reading: 99999.99 m3; 7 working pressure: ≤ 1.0MPa 8 Reading distance: ≤ 20mm 9 , read and write time: <3S 10 off valve time: ≤ 7S Xiaogan pre-paid water meters several features: 1. vertical, that is, Xinyang Xinyang meter parts no exposed electrode, moisture resistant, easy to use. User card after a two-key encryption, a card and a secret. 3 has a card table or a card table function. 4 the remaining water shortage, prompts the user to purchase water. With the battery voltage is too low, prompt the user to replace the battery. 6 with data read-back function, the card corresponding to the cumulative amount of water in a vertical meter, battery status, the number of interference back to read the management center. 7 small starting flow rate and high accuracy. 8 display function: parameters for the purchase of water, the remaining water, the cumulative amount of water can be effectively displayed on the LCD screen, the user can view the table in the remaining water and total water consumption information through the user card. Battery life of 6 +1 fourth Features ◇ with instantaneous flow display function can be read directly form the core of the instantaneous flow ◇ header from the case on the overall lending ◇ advanced micro-processing technology, instrument integration degrees and higher reliability ◇ a multi-card header has a non-linear correction function and data storage and query functions. ◇ signal output: pulse signal, 4-20mA analog signal and other signals is optional. ◇ flow range is wide, anti-interference ability, sand five main technical parameters ◇ Nominal Diameter: DN20-80-DN500; ◇ Nominal pressure: 1.6MPa-45MPa ◇ Accuracy: 2 ◇ signals output: pulse output signal amplitude 0V to 12V or 0V to 24V ◇ current output: Pulse output ,4-20mA standard current signal ◇ Operating voltage: DC3V ± 0.6V social development, the era of progress, with the development of electronic technology and communication technology automatic meter reading becomes possible to achieve technically. Xiaogan of the non-contact card prepaid water meter is the number of automatic meter reading system in a pre-paid meter RF card, RF card prepaid water meter Xiaogan RF card is used as the transmission medium of the water meter. Prepaid prepaid water meter, RF card water meter more closed than before. Waterproof, moisture better. Completely closed state, the the meter internal chip protective higher. The prepaid RF card water meter curb the malicious default part of the user. Non-contact in safety technology management using a non-contact card two three dispersed-based key management model to solve the security issues of key generation, distribution and storage. The following non-contact card Xiaogan prepaid water meter Main technical characteristics: pre-paid functions: the user to buy the water first, the arrears off valve without water. Card features: the one card meter, gas meter and water meter control. Synchronization features: LCD display synchronization and mechanical parts, even if the circuit fault LCD can not show, can also refer to the mechanical display. Prompted alarm function: battery voltage, water availability is insufficient, magnetic interference and fault information, the LCD will prompt alarm. Data upload function: each time the user to buy the water, put the information back to the management system, allowing management to understand the state of the water table. Valves self-maintenance functions: valve timing, cleared valve scale in a timely manner, to ensure the flexibility of the valve. Anti-hoarding water feature: software flexibility to set the lower limit of recharge, to prevent users hoard water. The blacklist Query: long time not to buy water users can be blacklisted, the inspectors users of water. Replace the battery: the bottom side of the water meter is designed to replace the battery cover, particularly convenient to replace the battery, replace the battery in bulk is no longer a pipe in the water sector problem. Waterproof function: (Xiaogan pre-paid water meters) in the process with a waterproof seal process as a whole, so you can work in a humid environment or short-term flood damage. Water supply water management mode, you can achieve the first payment for the water sector. The Xiaogan prepaid meter will help solve the problem of water charges owed, the use of computer technology in modern management, saving a lot of labor costs. 1, the working conditions of atmospheric pressure: 86kPa to 106kPa Ambient temperature: 5 ° C to 90 ° C Relative humidity: ≤ 90% minimum working pressure: ≥ 0.02MPa working environment no strong magnetic field interference, vibration and corrosive gases medium temperature: cold water table T30; Table T90 2 pre-paid installation of water meters installation location should avoid sun exposure, pollution, flooding, convenient disassembly and recharge. Newly installed pipeline shall gravel tube, flax and other debris to clean up and then installed water meter. The meter must be mounted horizontally, side upward; case on the direction of the arrow should be the same as the direction of flow. Meter may not be directly tied to the piping should exist between the active interface. The water meter installation in the boiler to the inlet pipe should be installed check valve. Note a proper use of interpolation / prepaid plug / moderate Prepaid expenses and the speed is not too fast, so as not to damage the card. not bending the card to avoid damage to the chip and antenna inside the card. c, not the card exposure, in a strong alternating electromagnetic field, high temperature, corrosion or other harsh environments. d, if the card is damaged or missing, please apply for a replacement card as soon as possible to share the water outlets. e Please keep table with shell was dry and clean to ensure the normal work of the table with. f, when cleaning with a neutral detergent, acids, alkalis are not allowed.
