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.

Rotary Piston Volumetric Type Water Meter characteristics, water structure, technical parameters and the composition of the material

Volumetric meter is also called the piston type water meter, is a constant flow type water meter. The national standard in the volumetric meter is defined as “installed in the closed pipe, by some to be a water meter chamber volume successive full known and discharge fluid and with fluid driven mechanism.

Rotary Piston Volumetric Type Water Meter

Volumetric meter with rotary piston type and disc type two series, when the water flow through the meter, the drive piston flow (disc) rotation (swing), and the piston cylinder (disk chamber) volume is constant, so, by counting mechanism measured piston rotation (disc swing) times, can get through the water meter water.

Rotary Piston Volumetric Type Water Meter is the main rotary piston type water meter, water meter disc type not used in domestic, abroad also only a few countries American etc.. Rotary piston type water meter is generally small caliber specification, is characterized by measuring high level (up to C grade and D grade), small flow measurement capability, high sensitivity. At present is mainly used for the measurement of pipeline pure water, water purification water to produce drinking water meter water Limited by Share Ltd Ningbo and Ningbo Donghai instrument channel limited company as the representative, in the water meter diameter is 8, 15 and 20ram. Volumetric meter repair debugging complex, high requirement on quality, used in China has not yet been widely.

Under the action of water pressure, water from the lower water inlet into the measurement chamber, center 3 driven rotary piston 7 surround the measurement chamber shaft to rotate, and the water from the piston blank and piston and the measuring chamber wall surface formed by the air flows to the upper outlet, at the same time the piston rotates, connected by a rotating shaft 4 and shifting fork 5 and counting mechanism, so as long as the note of piston rotation times, can flow through the water volume.

Volumetric meter generally refers to the ordinary rotary piston type water meter, has the advantages of high accuracy and sensitivity. At present, it is not yet in China such as velocity meter (impeller, turbine and so on) that is generally used, but is widely used in Europe and the United States and other developed countries, as the share of 50% in France, 77% in Britain, 79% in Sweden, American is 99.8%; while in China and the former Soviet Union is almost zero.

Characteristic.

1, the measurement principle of  Volumetric Piston Type Nylon Plastic Water Meter(Dry Register).

2, high sensitivity, can be in 1 liters / low traffic hours were measured.

3, horizontal installation reach D standard, non horizontal installation of not less than C class standards.

4, the counter by vacuum sealing, can keep clear reading.

5, moving parts are made of high quality materials, stable and reliable performance, long service life.

6, the built-in check back plate, which can prevent the countdown.

7, the case is made of stainless steel, beautiful and durable.

Error of Rotary Piston Volumetric Type Water Meter, characteristics, the main technical parameters and Principles

Volumetric meter is also called the piston type water meter, is a constant flow type water meter. The national standard in the volumetric meter is defined as “installed in the closed pipe, by some to be a water meter chamber volume successive full known and discharge fluid and with fluid driven mechanism.

Rotary Piston Volumetric Type Water Meter

Volumetric meter with rotary piston type and disc type two series, when the water flow through the meter, the drive piston flow (circle

Rotating disc) (swing), and a piston cylinder (disk chamber) volume is constant, so, by counting the measured piston rotation mechanism

Turn (disc swing) times, can get through the Rotary Piston Volumetric Type Water Meter of water.

Product volume type water meter is the main rotary piston type water meter, see figure C.5 and figure C.6 appendix C.
