Impeller Type Single Jet Pulsed Water Meter Class B With Pulse Output

Impeller Type DN25 Multi Jet Water Meters / Single Jet Water Meter With Pulse Output

The dry dial water meters use the multi-jet principle, also single jet principle available for smaller port size. This vane wheel water meter is known for its wide range, simple operation, and accuracy in cold water or hot water totalization and flow rate metering. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials. For pulse output, one of the dials is replaced by a gear, which turns a magnet that is detected by an encapsulated sensor threaded into the outside of the lens. Pulse rate is determined by the gear and the dial on which the gear is placed. Changing the pulse rate requires no special tools and can be done in the field.

Feature:

• Single-jet, dry-dial, free rotating register, small in size and light in weight;
• Magnetic drive, Resistance to exterior magnet interference,
• keep the reading clear in a long term service;

Note:

• Measuring accuracy conform to ISO 4064 class B standard..
• Available with different length on request. Available in hot water meter on request.

Working condition:

• Water temperature:0.1℃～40℃( 0.1℃～90℃ for hot water meter)
• Water pressure: ≤1.0Mpa

Maximum Permissible Error:

(1) in the lower zone from qmin inclusive up to but excluding qt is ±5%

(2) in the upper zone from qt inclusive up to and including qs is ±2%

(3) Hot water meter ±3%

Production line

Base water meter

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.
