4~20mA Remote Type Ultrasonic Level Meter 5-60M ultrasonic level gauge

Structure of product

Solid measurement

Installation flange

The installation method is the same as liquid measurement. It can install on the flange which joint the connected tube of container. The axis must aim to container outlet or perpendicular to the media surface, the probe should be able to come out of the connected-tube.

The ultrasonic level difference meter which has Chinese and English menu and simple

setup, can meet different requirements from customer. Normally, after followed installation instruction, then set several parameters, it will start to work.

Simple operation:

1. Key: Our products can be debugged through three keys on the panel. Then, the measured value is showed by LED.

2.After switched on of our product, press the SET key for two second and enter the first level menu.

3.The height value of probe(No.1) inputs to the “reference zero 1”, the “reference zero 1"position can be found structure table in the menu. (the height of probe is the distance from the launch surface of probe to the bottom).

4.The height value of probe(No.2) inputs to the “reference zero 2”. the “reference zero 2"position can be found structure photo of the menu.

5.Set “4mA ”corresponds difference value and "20mA corresponds difference value.

4mA corresponds difference value :output is 4mA, when the difference value equal to

setting value.

20mA corresponds difference value:output is 20mA, when the difference value equal to

setting value.

“As the corresponds difference value and "20mA corresponds difference value, please

check the structure photo of menu.

One. Application

Ultrasonic level difference meter (material, liquid), is used to measure height differences of level or material level in the two different of containers.

Three. Wiring

Electrical wiring of ultrasonic level difference meter

Terminal of ultrasonic level difference meter

Wiring instruction

Grounding: First ground terminal of instrument must be grounded actually. Do not share the

ground terminal with other devices. Pick up 4th Terminal. Transducer:Red: Trans_n transducer n

Blue: Temp n + temperature sensor +

Black: GND earth wire

single probe: n=1, double probes, n=1,2 Current:“current＋”connect mA n+;

“current－”connect mA n-/GND

single probe: n=1, double probes, n=1,2 Relay:RLlnA and RLnB show open;

RLnA and RLnC show closed. Single probe: n=1,2 double probes, n=1,2,3,4

Power: power AC connect L, N power DC: 24V+ connect 24VDC+,

GND connect 24VDC-

Note:

① Delay 1 is used for probe1 alarm, delay 2 is used for probe2 alarm.

Delay 3 and delay 4 are used for difference alarm.

② ★ The output of mA1+ and mA- is difference current.

The default output of mA2+ and mA- is probe 2 current or choose the probe 1 current.( select from “9 work mode”-------“2 the output of mA 2”)

★ As the running mode of double material level, the output of mA 1+ and mA－is probe 1 current. The output of mA2+ and mA－ is probe 2 current.
