1, use: 
 The total volume used to measure flows through the water pipe water meter and can be long-distance signal transmission amount of water to the secondary instrument, LCD water consumption. 

 2, features: 
 Far EasTone sender split meter rotor wet meter, easy reading LCD long-term to maintain a clear, high-precision, long life, and each flow through the 1 liter (10 liters, 100 liters) of water sends a signal, and can amount of water into electrical signals output pulse signal has a strong anti-interference ability. 
 The remote split meter is new products, using patented technology developed by the Ministry of Construction Recommended Products. 

 Main features: 
 LCD: microprocessor control technology is used for data acquisition and processing, using the LCD performance, reliable, fully functional, beautiful appearance, easy to use, easy to install, accurate measurement 
 2, the passive sender: no power will be able to output an ideal square wave signal, according to customer needs, you can use the two systems, remote transmission distance up to 20 meters. 
 3, high precision: the patented design to keep the switch structure to ensure that Far EasTone table hold function, to overcome the disadvantage of false signals due to water hammer and the critical point of fibrillation, the measurement accuracy meets: accurate signal transmission of the ISO4046 standard, to ensure that thousands of times the signal without errors. 
 4, antimagnetic: stainless steel housing, and add a shield, which can effectively prevent magnetic interference to prevent the occurrence of the Pirates of water phenomenon. 
 5, waterproof anti-theft: Far EasTone table with fully sealed structure, can be moisture-proof, waterproof; regardless of Far EasTone table is connected, reverse, can normal cumulative actual consumption, water meter put an end to reverse the phenomenon of Pirates of the water occurred. 
 6, long life: the whole remote split meter to achieve the life of ordinary water meter, Far EasTone part of the available ten years. 

 Conditions of Use: 
 1 Power supply: 3.6V/2.4Ah lithium battery 
 2, pressure: ≤ 1Mpa 
 3, the output signal: pulse signal (ISO4046 standard signal transmission is accurate) 
 , The water temperature: 0.1 ℃ ~ 40 ℃ (cold water sender water meter) 0.1 ° C ~ 90 ° C (hot water sender water meter) 
 5, the quiescent current: ≤ 10μA 
 Battery life: ≥ 6 years 
 Accuracy class: B 

 4, allowing the error: 
 1) From the lower zone including the minimum flow rate (qmin) to transitional flow rate (qt): ± 5% 
 2) from transitional flow rate (qt) to cover the upper zone of the carrier flow rate (qs): ± 2% 

 5, the installation requirements: 
 1, the installation of water meters should be preceded by clear stones, sand and other debris inside the pipe, to prevent meter damage, or failure. Debris more such as pipes or poor water quality, water meter should be installed before the filter; filter to regular inspection and cleaning, timely removal of accumulated debris. 
 2, so that the meter readings digital face on the direction of the arrow and the direction of flow must be consistent, the horizontal water meter must be mounted horizontally, vertical water meter must be mounted vertically (vertical meter points on the water and under water, orders need to explain). 
 3, the meter must be installed in a dry, frost, and easy maintenance. Must be installed on the valve water meter before and after 
 4 meter upstream and downstream to install the necessary straight pipe or its equivalent flow straightener upstream straight pipe length of not less than 10 times the meter nominal diameter, the length of the downstream straight pipe of not less than five times the water meter nominal diameter.
