TDS-F wall-mount Ultrasonic flow meter clamp-on or insert type

 

Ultrasonic flow meter is designed to measure the velocity of liquid within a closed conduit.

 

TDS-100F series ultrasonic flowmeter Applied to on-line measure and system monitor for nearly all liquids from petrol, chemical, metallurgy, electric power plant, irrigation, city water company, energy monitor fields, realize the functions of measuring and checking of flow velocity, flow rate, accumulation and heat quantity of different liquids, and flow rate on/off, liquids distinguish

 

Flow transducer:

 

The main board is suitable for any kinds of transducers, including clamp-on type, insertion type, ¦Ð in-line type, standard in-line type and same kinds of transducers from other manufacturers. 

 

Principle of Measurement  

When the ultrasonic beam is transmitted through the flowing liquid, there will be a difference between the upstream and downstream transit time (travel time), which is proportional to flow velocity, when fluid is flowing, counter flow transit time is more than direct flow transit time. The formula as below. 

Remarks:   

¦È     The angle between the ultrasonic beam and the flow

M     Transit times of the ultrasonic beam  

D     The internal diameter of the pipe 

Tup   Transit time in the forward direction

Tdown Transit time in the reverse direction  

¦¤T=Tup ¨CTdown 

F=900¡Á¦Ð¡ÁD2¡ÁV

 

Wall mounted fixed style ultrasonic flowmeter transducers include clamp-on type, insertion type, in-line type. 

 

Technology features:  

1)    operating power: AC 85¡ª264V or isolation DC 8-36VDC 

2)    repeatability: better than 0.2%.accuracy: better than 1% 

3)    signal Output: one channel standard isolation RS485 output 

        i.   One channel isolation 4-20mA or 0-20mA active output. 

        ii.  One channel OCT output (programmed between the pulse widths (6-1000ms), default (200ms)) 

       iii.  One channel isolation relay output, with positive, negative, net accumulation pulses and different alarm signals. 

 

4)    Signal input: two channel three wire system PT100 platinum resistor input loop, to make heat meter has the function of displaying heat quantity. 

 

     i.  Three channel 4-20mA input optional, accuracy: 0.1%, has the ability to input the signals of pressure, liquid level, and temperature and so on.  

 

5)    Display: 2*20 backlit LCD(Chinese and English optional) 

 

6)    Operating: 4*4 tactile keypad  

 

7)    Other functions: automatic memory the positive, negative, net totalizer flow rate and heat quantity of the last 512 days, 128 months, 10years.

 

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

 

8)    Protection level:mainframe:IP65, transducer:IP:68 

 

9)    Transducer: clamp-on type, insertion type, in-line type. 

 

 

Optional accessory: 

 

1: clamp-on transducer (standard S1 style, standard M1 style, high temperature S1H, high temperature M1H) 

 

2: insertion transducer (standard insertion B, cement insertion B)  

 

3: in-line type transducer (hygienic style, ¦° style, standard style) 

 

4: special shielded twisted pair cable 

 

5: strap (applied with installation of transducers on cast iron, GRP, PVC, etc. that cannot be welded directly).

 

 

 

 

 

 

 

Insert type transducer:
