 TRG8020 guided wave level transmitter on TDR principle for tank vessel  

 

 

  

 

GWLF can be used for measuring level or interface with 4-20mA standard current signal output. The measuring accuracy is not affected by change of density or dielectric constant of medium (in the setting range). It is easy operating and maintenance. It only needs to be entered configuration data into the instrument and no need to change the liquid level at field. So, GWLF is a new type of level (interface) measuring instrument.

 

Output signal: 4 ~ 20mA or 4 ~ 20mA + HART, applicable within 3.8 ~ 20.5mA

Resolution: Analog: 0.01mA, Display: 1mm

Accuracy: 5mm or 0.1% FS for coaxial probe

Range: 600mm ~ 6000mm or 1000mm ~ 22000mm

Load resistance: Max. 650Ω(24VDC)

Damp: 0-32s adjustable

Diagnostic alarm: 3.6mA, 22mA, hold (Note: when both HART protocol and field indicator are selected, 3.6mA diagnose is not available.)

User interface: 3 keys, LCD or HART communication

Dandong Top Electronics Instrument (Group) Co., Ltd (hereinafter referred to as DDTOP Group) locates in Dandong City. The total registered capital is RMB 5.07million, area cover 32000 square meters,construction area more than 15800 square meters . Currently total employees are around 350, and there are 98 R&D employees.

DDTOP Group is a private joint-stock company which is specialty in developing, manufacturing and marketing of automatic level instruments, flow meter calibration system, magnetic drive pump and so on. Established in 1992, Dandong Top Electronics Instruments Co.,Ltd is the parent company of DDTOP Group. DDTOP Group dominates “Dandong Top Measurement and Control Co.,Ltd”, “Dandong DDTOP Manufacture and Trade Technology Co.,Ltd”, “Dandong Top Pump Co.,Ltd”, “Dandong Top Instrument Control System Co.,Ltd”, and “Shanghai Top Electronics Instrument Co.,Ltd”. The products of the Group are well sold inland and overseas, building up our own brand especially petroleum & chemical industrial. Now the main clients in China are: CNPC, SINOPEC, CNOOC, CHEMCHINA, SHENHUA GROUP, STATE GRID. Products are exported to many petroleum industrial companies in Middle East, Bulgaria, Algeria, Sudan, India, Brazil, Mexico and so on.

Our mainly products are level (interface) transmitters, flow transmitters, liquid controllers, flow meter calibration system, field control system, magnetic drive pumps and so on.

Meantime, DDTOP Group is the biggest OEM for FISHER displacer lever transmitter all over the world (OEM = Original Equipment Manufacture). Depth technical communication is organized every year, in order to strictly control the product quality of each link of the process. Currently DDTOP annual sale of FISHER displacer level transmitter is around 2000 sets.

Our goal is to build up “A famous Chinese brand devoted to the world”. Hope there is chance to cooperate.
