NYLD-S Electromagnetic Water Meter
The NYLD-S electromagnetic water meter is a battery-powered electromagnetic induction water meter which can be installed anywhere without sacrificing accuracy and performance. It does not require the main power supply.It is specifically designed for individual water applications such as water withdrawal, pipe network distribution, metering charges and irrigation. It has intelligent information and high measurement performance, which is easy to install and saves user investment.
The NYLD-S electromagnetic water meter (also known as battery power supply electromagnetic flowmeter) adopts internal battery power supply without external power supply, which is suitable for the field power grid cannot reach and difficult power grid laying, especially for the monitoring, measurement and settlement of tap water supply system.HBLD / D battery power supply electromagnetic flowmeter converter, using ultra-low power circuit technology design efficient and reliable excitation, signal processing circuit measurement function, to ensure that the converter has high reliability and stability, at the same time using efficient system management technology to greatly reduce the system power consumption, save power supply cost while realizing accurate measurement.

NYLD-S Electromagnetic Water Meter Classification
show | Three lines of display: using 120 segment code display, can realize the flow speed, flow, total amount, billing, alarm information, battery power and other data and information display.Display content is selectable and can be switched without the magnetic spring switch to operating authentication. |
Internal cumulative calculator | For the total forward flow, the total and net reverse flow can achieve an 8-bit cumulative calculation. |
Programming | If the data is provided to the Company upon ordering, the relevant data will be prepared inside the converter before leaving the factory.When necessary, it is easy to reprogram the converter through the communication interface by the upper computer or the operator authorized by the user, and it will not affect the technical performance of the converter. |
Communication mode | RS 485 Communications |
Reactive mode | Excitation frequency of 1 / 15Hz; 2.5Hz excitation frequency; other optional |
Power Supply Voltage | Standard configuration: 219Ah 3.6V high-energy lithium battery (not
rechargeable) |
Battery life | Two 19Ah high-energy lithium battery with 1 / 15Hz excitation
response for 5 years |
Report to the police | Battery-powered type electromagnetic flow meter can monitor the following alarms: air traffic control alarm, sensor fault (excitation open circuit), reverse flow, upper and lower flow alarm, and battery depletion.After programming the alarm, the instrument can display the corresponding alarm information after the above alarm and can indicate the alarm information to the computer computer through the communication interface. |
Temperature | Operating environment temperature: -25℃ ~60℃ ； |
Protection against the external environment | One body size reaches IP67, divided into body size converter IP67, sensor IP68 |
Data parameters | Instrument parameters and measurement data are stored in
non-volatile memory (generally stored for 10 years)For the use
requirements of measurement and settlement, the instrument has
mechanical seal and electronic seal two devices can effectively
prevent it |
