Wooden Case of GSM Module Double Channel Ultrasonic Water Meter
GSM Module Double Channel Ultrasonic Water Meter
Dual Channel ultrasonic water meter is according to China's national water meter standard GBT 778.1-2007, the international standard ISO - 4064 - meter and 05, the ministry of construction, electronic remote meter CJ / 224-2006, IDT standards such as the latest research and development of the battery power supply of large diameter double track ultrasonic water meter.
The water meter adopts the latest development of characteristic of ultrasonic transmission phase and time difference measurement technology, with high precision, low power consumption, wide measuring range than the remarkable characteristics, stable and reliable, etc
By the IP68 parts in structure scheme, namely every part to achieve IP68 protection grade, instrument cavity even water can guarantee work for a long time.
This series of water meter solves the traditional meter idling, small flow rate measurement. Can be widely used in urban water supply pipeline, total household water table, water, farmland irrigation water monitoring, at the same time is also suitable for a variety of industrial field.
l Pipeline design for fluid layered double track measurement, measurement is accurate.
l Range than wide, and less than 0.01 m/s pick up traffic.
l Shows that large amount of information, with screen display 9 digits cumulative flow and four digital instantaneous flow rate.
l Design concept and energy saving, such as air or fluid static state for a long time under the instrument will automatic power saving function.
l IP68 protection grade design, all parts completely sealed protection, even water can work for a long time.
l Design on the time of year, month, day have a cumulative record and collect data function.
l Has a variety of modes of communication interface; TTL level pulse output and USART interfaces, convenient connection other low-power devices; Standard RS485 interface; Infrared communication interface; Support CJ - 188 communication protocol.
l Support the standard MODBUS, M - BUS, HART communication protocol, communication protocol of compatible haifeng ASC Ⅱ yards.
l Output signal in a variety of ways: isolation of the pulse signal output available two road, (including pulse equivalent and programmable pulse width); Can two wire system 4-20 ma output.
l With functions of software update online.
l Has the dual PT1000 temperature measurement function, can realize heat metering.
l Built-in quantitative controllers, can achieve manually or set the time automatically start controller, and then realize automatic timing quantitative water or irrigation.
l According to the different needs of customers with a variety of system selection, including cubic meters and us gallon, cubic feet, and litres.
l Built-in lithium battery, six years of battery life
