Intelligent water meter/IC card water meter Battery

IC Card Water meter/intelligent water meter is an intelligent water meter products, at this stage has begun to promote the application of many pilots, because it is necessary to install the battery, to work, display data, so some users have produced such questions: if the IC card water meter/intelligent water meters is power off, will the water supply be cut off?

Multi Jet Water Meter     Prepaid water meter  

intelligent water meters need to recharge to buy a drink to use, after buying water on the meter inserted IC card, to water. However, in the use of the process, because of forgetting to replace the battery, many users found that the insertion of IC card, LCD screen has not shown the number, at this time will occur two kinds of possible problems, one is inserted card, water meter does not show the number, but the supply of normal tap. There will also be a situation, that is, immediately water. What are the reasons for these two different situations? This is because the IC card water meter/intelligent water meter motherboard battery and panel battery is different, if the LCD is not displayed, and will not affect the user normal water, at this time the user should replace the battery as soon as possible. And if the real water supply in the home, then there is almost only one reason, that is, intelligent meter monitoring to run out, automatic to the brake plate issued a signal.

2, press the buckle, unplug the connector, disconnect the battery snap connection. Water meter used for two 3V lithium battery, model CR14505E two series, the battery and the water meter by the buckle connection.
3, the new battery to buy, pay attention to whether the positive and negative batteries with the original battery, mainly to see the connection line. If correct, plug the buckle with the water meter can be inserted.
5, at this time without worry on the battery cover cover, first with their own water card into the water meter, insert the water meter after the solenoid valve action, the screen shows the relevant figures, that the battery work properly, the water meter can work. Note: There may be a small amount of water in the water meter.

Drinking Water Measuring Instrument( Water Meter) performance characteristics, technical parameters, the working principle, product introduction and use

Multi parameter water quality detecting instrument design is excellent, very convenient to use. Can automatically compensate the error caused by temperature changes due to measurement. The instrument measured PH, mV, C, EC, CF, TDS value, can be read by the liquid crystal display apparatus, display and backlight function.

Drinking Water Measuring Instrument( Water Meter)

PH: pH

ORP: redox (unit: mV): the amount of bacteria, the disinfection effect “of =650mv measure

Electrical conductivity (ms/cm): salt, ion, impurity content. The very low

CF: concentration of reverse osmosis device.

Whether it contains water, mineral and trace element is the key to determine its acidity. The pH of water is contained by the ion water decision. The Drinking Water Measuring Instrument( Water Meter) of the acid strength, is indicative of ion activity. Natural water pH value between 7.0-8.0 in general, weakly alkaline; pure water pH value between 5.0-7.0 in general, acidic substances acidic amount of active in the body will make the body’s internal environment deterioration, the blood acidic, appear very unhealthy “acidic” exceed the standard easy hair fat, calories, health hazards. Acidic, alkaline food collocation is very important to human health, the normal human body fluids, including blood: intracellular, extracellular are weakly alkaline, pH of the blood is 7.35 ~ 7.45, when the pH value below 7.30 will make the body showed “acidic”, often with acidic food intake, will the body and the lactic acid increased due to the digestive organs of the excitement, will increase the body of calcium, magnesium plasma consumption, causing these nutritional deficiencies, and dental caries susceptibility. “Acidic” harm, often eating fatty food, make the body acidic substances accumulation, blood is acidic, the body’s internal environment began to deteriorate, appears very unhealthy “acidic”, dizziness, constipation, insomnia, anxiety, fatigue, decreased resistance, susceptible to upper respiratory tract infection. Because the blood viscosity increased, also can cause arteriosclerosis. In addition, only humoral pH is normal, the body cells and immune cells have the ability to engulf and destroy the cancer cells, cancer cells surrounding the pH value is 6.85 to 6.95, partial acid, survival and normal pH value is not conducive to cancer cells. Moreover, the body pH every drop of 0.1 units, insulin activity is decreased by 30%, which increases the risk of type 2 diabetes. Acidic foods too much influence intelligence British scientists found that: human brain fluid acid-base properties related to intelligence, that is in the range of body fluid pH within the allowed (i.e., pH value of 6.8 ~ 7.5, the acid is too high (low pH) low IQ; alkaline high IQ (PH high).

PH is a measure of the pH scale, in many ways to control the pH, these places need to know the pH value of the solution

PH is one of the most important Rotary Piston Volumetric Type Water Meter of water solution. Natural phenomena involving an aqueous solution where. Chemical changes and production processes are related to pH value, therefore, in industry, agriculture, medicine, environmental protection and scientific research field needs to measure pH value.

The acidic aqueous solution, Ph<7, pH value is small, said more acidic; alkaline aqueous solution, Ph>7, the bigger the pH value, alkalinity more strong.

Features Drinking Water Measuring Instrument( Water Meter), principles, introduction and use of traditional

Measurement of water flow meter. Mostly is the cumulative flow measurement of water. Generally divided into volumetric meter and velocity meter two. The accuracy is higher than, but the high requirement of the water quality, water containing impurities easily blocked. Recording water water meter, installed in the pipe, when the user when discharging water, table rotation pointer or wheel pointed out that through the water.

Drinking Water Measuring Instrument( Water Meter)

The internal structure of the traditional water meter from the outside to the inside can be divided into the shell, the inner core sleeve, three piece. The shell is made from pig iron, water inlet out through the lower part of the annular space shell, here called “ring room”. On top of the annular space of the “upper room” and the Drinking Water Measuring Instrument( Water Meter). One with a hole at the bottom of the filter sleeve, filter water impurities. The side of the sleeve has two rows of round holes, the hole position coincided with the shell on the annular chamber to, obviously, the lower is the water inlet, outlet row is. In particular, the two rows of holes are sideways along the tangential direction round. Note on two rows of holes in the opposite direction. Water from the discharge hole along the tangential direction of flow in, will form a rotating water flow, this is very important for water works. The inner core is divided into upper, middle, lower three layers, see from the glass of the window is the upper, only the pointer and dial. In fact, the key is lower, there is a plastic wheel, there are many plastic blade wheel, called “impeller”.

Impeller location right in the rotating stream formed by the lower hole of the casing, the impact of water flow blades, wheel torque is generated, so that the rotation of the impeller. The tap was greater, the more anxious, impeller will turn faster.

The impeller shaft vertical upward to the middle, there is a small gear on a shaft, use it and “decimal gear meshing, achieve” to total revolution. “The decimal number gear” role is when the single digit gears turn ten laps, ten digit gear will turn a circle. In other words, a digit gear rotates a circle, the ten digit gear will turn 1/10 times. A number of gear are active, rely on it to drive ten digit gear. In fact, every decade with two on gear, so that the rotation direction, wherein a pair of transmission ratio is 9:30, another is 10:30, the two together, the total transmission ratio is the two product, namely 0.099999, can approximate to 0.1. According to this calculation, if you want to read (seven digits before the decimal point read four black scale after the decimal point, read three red scale), have 12 pairs of gears. Plus some other purpose, in the middle and small space into 18 shaft and 34 gears, also can be a high density mounting. This type of meter with its simple and cheap, can be used without the need to repair in damp environment, without power supply, power failure does not affect the work of the advantages will still long service.

The term:

The minimum flow rate (Q1): showing the value of the maximum permissible error meets the minimum flow requirements of water meter.

The boundary flow (Q2): appeared in between, commonly used flow Q3 and minimum flow Q1 will flow range is divided into the two region specific maximum permissible error of “high” and “low” flow.

The commonly used flow (Q3): maximum flow rated working conditions. In this flow, water meter should work normally and meet the maximum permissible error.

Overload flow (Q4): water in a short time can meet the requirements of the maximum Rotary Volumetric Piston Water Meter, maximum flow in rated working conditions can still maintain the metrological characteristics.

Pressure loss (Δ P): at a given flow rate, head loss caused by the existence of water pipeline
