Aichi SU electromagnetic water meter （DN40-300）

·Residual excitation

When the product is working, only intermittent power supply is needed to ensure the continuous generation of magnetic field, and the power consumption is only one tenth of that of similar electromagnetic water meters. The breakthrough in excitation technology has resulted in the excellent metering performance of the product and the long-term reliable use of the battery. The excitation interval of the SU electromagnetic water meter reaches 0.3 seconds per time, which is 1/50 of that of traditional electromagnetic water meters, while the battery life can still be guaranteed for more than 10 years.

·Fully automatic message calibration

Before leaving the factory, the product is calibrated using a unique 8-bit message output method, with each meter calibrated for more than 8 hours. All flow parameters are automatically calibrated using software to ensure flow, repeatability, and consistency.

Excellent Performence

·Accurate measurement

·It can simultaneously monitor both ultra large and ultra small traffic. The conventional product R400 and customized product can reach R800, with an accuracy level of up to level 1.

·There is no calibration mode, and the measurement interval during actual use is consistent with that during calibration, both of which are 0.3 seconds per time.

·The external environment has almost no impact on traffic, dispelling the biggest doubts about the use of electronic large meters.

Comparison of excitation methods with other battery driven electromagnetic water meters

·Check for leaks&Reduce energy consumption

The unique instantaneous flow active high-frequency output method (transmitted every 1.8 seconds) has brought massive and effective analysis data to water management.

·Accurate leak detection with minimum instantaneous flow rate

When measuring and detecting pipeline leakage in DMA zones, the product can accurately capture the minimum instantaneous flow rate at night, effectively determining whether there is pipeline leakage and the exact amount of leakage. This method has high leak detection accuracy, low implementation cost, and strong environmental adaptability, subverting traditional leak detection methods. Other similar products are limited by power consumption and generally upload data every 15 to 30 minutes. The minimum flow rate can only be based on the average flow rate or the current instantaneous flow rate between collection intervals. It is easy to make plausible judgments about the actual leakage situation of the pipeline network.

·Maximum instantaneous flow helps reduce costs and increase efficiency

In secondary water supply, there is a range of operating conditions where the pump achieves the highest efficiency with the lowest energy consumption, and a scientific and reasonable pump model needs to be selected based on the water supply volume of the area. The product can capture the maximum instantaneous flow rate, providing crucial guidance for analyzing the relationship between pump flow rate and head, as well as pump power. It helps water companies significantly reduce pump energy consumption costs, improve pump operation efficiency, and help achieve the dual carbon goal.

·Long Life

·Without any rotating parts, the lifetime measurement accuracy is unchanged, and the measurement error is eliminated. Low noise amplification signal is used to optimize the magnetic flux, which will not delay the velocity signal caused by the deposit, and effectively solve the measurement error caused by electrode junction.

·The battery life is more than 10 years, and the warranty of the whole machine is 8 years (from the date of factory delivery).

·A strong epoxy powder coating (Teflon rubber is used for most similar products) is attached to the measuring pipe wall, which can better ensure that the flow field will not be impacted by impurities in the water and lead to deformation, and ensure the long-term accuracy of measurement.

·The case is made of 316 food grade stainless steel and the body is of high sealing structure (IP68), which can prevent electronic components from being exposed to humid environment and ensure long-term and stable accurate measurement performance.

Up to 10 years of use, the measurement error curve is almost identical to when newly installed
