Large Size Prepaid Smart Water Meter Commercial Built In Microcomputer

Large size DN50 RF type IC card Prepaid Water Meters for water utility billing, Multi jet water meter type

The large size Smart prepaid water meter, is up to DN300 for commercial and industrial water supply billing purpose, it adopts a contactless IC card to store water volume and monitor water consumption. Customers purchase water volume at vending points and upload water volume by swiping his IC card on the induction area of installed water meter inside or outside home to activate valve, which will open automatically to supply water.
During the period of water supply, the built-in microcomputer of water meter will automatically check and subtract the used water volume. Water meter has twice alarm function, when the purchased water volume reaches to alarm volume, water meter will close valve and stop water supply. Customer can resume water supply by swiping his IC card on water meter. When the remain water volume is used up, water meter will stop water supply completely and the customer needs to charge his IC card again.

Available in sizes 15mm to 25 mm with nominal flow rates of Qn 1.5m³/h to Qn 15m³/h. It's for cold water volumetric measurement, or hot water up to 90 ℃.

Functions

• Prepaid, avoid owing and consciously refuse to pay bill
• High accuracy of measurement
• Environmental protection material and can guarantee water quality for drinking
• Programmable tariff set
• Waterproof, moisture-proof and anti-attack
• Adopt replaceable batteries, change batteries by customer themselves, more convenient.

Key features

• Contactless IC card (RF card) technique: adopt our company’s patent technique of RF card, transmitting data by wireless way, waterproof, moisture-proof and anti-attack
• Electric floating ball valve technique: adopt electric ball valve technique, work reliably and lower loss of pressure
• Totally sealed design: all the circuits are sealed by high performance casting glue, so there is no exposed electrode, and can be used in moist environment
• Anti-attack of strong electricity or magnetism: water meter will close valve automatically when being attacked by strong electricity or magnetism
• Micro-computer and microstorage technique: high integrated and high reliability

Product data sheet

Installation

• The installation of water meter meets the installation requirements of ISO4064-2:2005
• The caliber of water meter shall correspond with caliber of pipes and the used flow rate is less than or close to the permanent flowrate. The installation place should avoid exposure, flooding, freeze and pollution, and convenient for installing, removing and reading data.
• The water meter shall be installed horizontally (display surface is upward).
• The sands and stones and other sundries in the pipelines shall be cleared.
• The arrow on the water meter should be the same as the water flow in the pipeline.
• If the water meter is installed on the inlet of the boiler, it is better to install inverted valve on the outlet of water to prevent the return current of hot water and steam will damage the water meter.

Competitive Advantage:

• Compliance to international standards: ISO4064 / GBT778 / Q/320700JR05-2003
• Strict process control
• Advanced calibration equipment
• Engineer team

Production line

Shanghai I Fluid Technology Co., Ltd, a technique based company. We focus on the deployment , installation and management system of smart metering and smart grid in all utility sectors, include but not limited to water, heat, gas and electricity.

To adapt to the global environment protection trends, and China government policy, China put the green energy application and EIA at their first place. We do our best contribution to the government energy saving policy.

We put emphasis on central air conditioning system, energy distribution system in separated areas, green energy application in commercial buildings, municipal water / gas / heat supply, sewage discharge monitoring, and many other industrial applications. Adhere to the principle of “ low carbon energy, build future”, we aim to give solution to take the best avail of natural resources, improve energy efficiency, reduce energy consumption. Through more renewable energy, reasonable energy store technique, and minimize energy demands, we help our clients to build an intelligent low carbon energy network. Build the optimized electricity, heat, water and gas supply and demands system, finally to realize the LOW to ZERO energy system.

Over tens of years developing, we design and manufacture a complete set of energy relating products: central air condition with variable ventilation and ventilate at low temperature, flexible central air conditioning, cooling store capacitor, AMR/AMI, metering and level products.
