Product Introduction:

The electronic hot water meter produced, manufactured, and sold in Shenzhen specializes in measuring hot water or hot spring water with a temperature below 100 degrees Celsius. This product has accurate data reading and excellent waterproof function. All water meters are divided into cold water and hot water, and their functions are the same. Cold water meters have the same functions as hot water meters. However, the cold water meter cannot measure hot water. The electronic hot water meter adopts an integrated structure design, which is convenient for management and particularly suitable for public places such as student apartments, office buildings, and collective dormitories. As an on-site water supply fee settlement tool, it has the characteristics of prepayment and tiered water pricing.

[Three]Price reference for electronic hot water meters: Household models with valve control are generally priced between 185 yuan and 200 yuan per unit; The one without valve control is a bit cheaper, priced between 120 and 140 yuan per piece.

【4】 Execution standards for electronic hot water meters:

1. This standard was developed with reference to GB/T 778.1 "Measurement of closed full pipe water flow - Drinking cold water meters and hot water meters - Part 1: Specifications";

2. GB/T 15464 General Technical Conditions for Packaging of Instruments and Meters;

3. CJ/T 224 "Electronic Remote Water Meter" and CJ 266 "Safety Rules for Drinking Water Cold Water Meter".

【5】 Installation and usage instructions

(3.1) The installation of the water meter must make the dial face up, and the direction of the arrow on the case should be consistent with the direction of the water flow in the pipeline. A control valve should be installed upstream of the water meter for easy maintenance;

(3.2) The installation of the water meter must follow the prompts on the water meter dial. Those marked with "H" are installed horizontally, while those marked with "V" are installed vertically;

(3.3) Installation will cause the threaded connection end or pipe joint or connecting nut of the water meter to break and be damaged. If the spacing is too small, the water meter cannot be installed. If the two end pipelines of the water meter are not on the same axis, other means should be used to correct the pipelines to be on the same axis to meet the installation requirements of the water meter.

After installation, place the card in the sensing area and wake up the water meter. The water meter will scroll to display water usage, total water usage, remaining water usage, etc. The specific sorting depends on the program written by the manufacturer. If the water fee is a multiple rate, after inserting the card, the LCD screen will display the remaining water fee.

The main advantage of electronic hot water meters is that each household has its own meter, and water can be used with a card. In the card data input table, the water meter automatically opens the valve to supply water, and after use, it automatically closes the valve to cut off the water supply. Users must pay a new fee to purchase cold or hot water before they can use it again. The electronic hot water meter can also record the operation status of the meter, and manage the total water consumption, total purchased water, switch valve status and other information of the meter under the management machine or management software. Smart water meters can improve management efficiency, effectively prevent arrears, avoid on-site meter reading, and achieve water conservation.
