Double Header Electromagnetic Water Meter DN40-50
Overview
DG-FW001 Series electromagnetic water meter is a flow measurement system which is composed of electromagnetic flow sensor and converter, which is specially used in the trade measurement and community examination and measurement of the commercial and industrial users of the water company, to meet the urban water supply, to ensure the accurate calculation, and widely used in the field without power supply place.
Pipeline leakage is a difficult problem for most water companies.It is also one of the important reasons for the high gap in water supply production and sales.Through the small flow analysis at night, it can effectively reduce the leakage rate, assist the water company to reduce the production and sales gap, improve the work efficiency, and realize the turnaround of the loss.Generally at night, the user's water consumption is the lowest, and the quantitative leakage is the most accurate at this time.
At present, the water supply status of most domestic water companies is that the design of pipelines on the pipe network is too large, so the flow velocity in the pipeline is very low, especially at night.
No matter the large flow during the day or the small flow at night, Degao Electromagnetic Water meter can achieve high accuracy. The small flow rate is very good, which can solve the problem of unreasonable meter selection.
Feature:
High R value
Electromagnetic Water Meter has Ultra Wide range ratio Q3/Q1=400, Q2/Q1=1.6, regardless of daytime large flow, or night small flow, can achieve high precision, small flow metering is very good, can solve the problem of the selection table unreasonable.
Low starting velocity
The starting velocity ≤5mm/s, accurately capture the night small flow, solve the problem that the traditional water meter does not measure small flow.
No straight pipe
In the case of two elbows, no straight pipe sections can be installed or buried (designed for two water supply application environments).
Ultra-strong anti-interference
Strong electromagnetic interference ability, in a strong electromagnetic environment, to ensure accurate measurement. Encounter inverter, pump and other serious interference source, the meter can still be used normally.
High reliability
Electromagnetic Water meter inside for straight pipe structure, no pressure loss, no mechanical water meter may appear pull table and card table phenomenon.
Long service life of lithium battery
Ultra-low power design, average power consumption <2.5mw to ensure battery life of more than 6 years.
Long-term high-precision measurement
DG-FW001 series of electromagnetic water meters even if not in accordance with the comprehensive examination each two years, but also can ensure the accuracy of measurement.
Patent anti-Disassembly design
Patent anti-theft table cover, table seal once opened, it will alarm, prevent the theft of the meter and tampering instrument data.
Easy installation
After the installation of the water meter, no need to set the instrument on the spot, convenient and quick.
Good compatibility of meter reading system
Excellent meter reading system compatibility, can be compatible with some domestic manufacturers of far copied table system, to avoid the waste of resources for customers.
Measurement of the available pressure
Multi-parameter detection and Internet technology can simultaneously detect pipe network pressure, flow, etc.
Optional meter Reading Mode
DG-FW001 series electromagnetic water meter optional GPRS module directly connected to the customer's industrial control system for reading meter.
Horizon is very stable
DG-FW001 series of electromagnetic water meters' horizon is very stable, just need a little maintenance, to ensure that the instantaneous flow is zero when the users aren't using water, to avoid the resulting charges dispute.
Food Grade Lining
DG-FW001 series of electromagnetic water meter using food-grade PTFE lining to ensure that the water safety reference.
Straight readings
Mechanical water meter can't directly transmit instantaneous flow data, DG-FW001 series of electromagnetic water meters can read meter memory instantaneous flow and cumulative flow directly through the RS-485 or GPRS, convenient and accurate.
It will report when each change happens
DG-FW001 series of electromagnetic water meter have a powerful alarm function: battery power, water exceeding the limit, mutation, not full pipe, etc. can be changed to alarm, so, the water anomalies of large users can be found in time.
Diving design of the whole machine
DG-FW001 series electromagnetic water meter machine IP68 diving line design, can be long-term underwater work.
Complete stainless steel design
DG-FW001 electromagnetic water meter complete stainless steel design, in addition to the appearance of neat and beautiful, but also to ensure that the instrument perennial in the dark and humid and other complex operating conditions reliable operation.
