New version TDS-100W battery power style ultrasonic water meter achieved to display online on spot,TDS16 mainboard is encapsulated in the sealed body(the size is the same as in line type meter),the measuring mainframe can be welded on

the measured pipe or hang up on the wall.it features with lower starting flow,wide measuring range ratio,higher accuracy,long lifetime.

Technology features:

1:operating power:3.6V/19AH Lithium battery

2:measuring cycle:500ms—49 seconds(default before leaving factory:10 seconds)

3:sampling times:optional sampling times for one cycle(32---128)(default before leaving factory:64)

4:battery consumption:the battery can work continually up to 5 years under the condition of default

5:optional output:one channel USART(TTL)output

One channel non-isolation RS485 output(the built-in 3.6V battery supply power,at the state of accepting,there is no power consumption.only at the state of sending datas,there is power consumption.but the interface is not electrical isolation,it

is easy to be disturbed to make the flow meter work that is suggestion for users to use TTL to output when networking,RS485 is used to setup parameters)

Two channel isolation OCT output(programmed between the pulse width(6-1000ms),default before leaving factory (200ms))

One channel bidirectional serial port for general peripherals,directly through series connection to connect peripherals just like 4-20mA analogue output board,frequency signal output board,thermal printer,data logging meter,etc.

6:input optional: two channel two wire system PT1000 platinum resistor input loop,to make heat meter has the function of displaying heat quantity.

7:display:96 segments LCD ,display 44 different Menu windows.

8:operation:magnetic two keypad,browse prior 40 windows datas,but can not setup parameters,in order to setup parameters,you have to connect with another meter or PC setup parameter software(download from our website) through RS485

9: other functions:automatic memory the positive,negative,net totaliser or flow rate and heat quantity of the last 512 days,128 months,10years

Automatic memory the time of power turning on and off and flow rate of the last 30 times, realize to compensate by hand or automatically,read the datas through Modbus communication protocol.

10:protection level:IP68

11:replacing directly.

12:transducer:clamp-on type,insertion type,in line type

Low power ultrasonic water meter is designed according to Europe alliance EN1434 standard and ultrasonic time-difference

principle. It can instead of other water meter and it has other characters: high accuracy、better reliable、no moving part、no need

to set data，install in any angle.

Ultrasonic time-difference principle

Measuring water or other liquid

Accuracy : ±1%，±2%

Repeatability : 0.5%

Measuring period: 3S，1~31S(selection)

Battery can work 6-10years，or two line power

Lowest measuring velocity of liquid 0.01m/s

No pressure lost and moving parts，no nursing for 10 years

Pipe length designing according to the normal water meter

IP68，can working under water lower than 2 meters

Foundry in mould ,no reveal

DN15-1000mm

Ceramic sensor apply to －40℃~160℃

Over look type、normal type、separate type
