Product Description

External Installation Non Contact Ultrasonic Tank Level Indicator ( A+E 69L)


External Installation Non Contact Ultrasonic Tank Level Indicator

Product Description

This tank level indicator is a measuring instrument which utilises ultrasonic signals for the precise level control and measurement of liquids. The sensors are attached to the outside of the tank and measurements are made through the tank wall. There is no need to drill holes or to perform any welding to install the sensors.
Since there is no contact between the sensors and the liquid to be measured, the tank level indicator is ideal for hygienic applications and for the measurement of aggressive media.


--No need to drill holes on the tank, external installation.

--No contact with media, completely non-invasive.

--Applicable for  poisonous, corrosive, high pressure, flammable, explosive, volatile, easy leaking liquids, etc. 

--High accuracy up to 0.2%FS.

--Unique two wire system, easy for wire connection.

--Non-contact measurement to make it safe and long working life.

--Easy and low cost installation and maintenance.

--Self-diagnosed function to make the meter stable and reliable.

Application Requirements

1. The liquid meida should only contain a small amount of gaseous or solid content. The tank bottom should be free of or be covered only by a little amount of deposit material.

2. When the media dynamic viscosity is between 10mpaS and 30mpaS, the mearuing range would reduce. When it's greater than 30mpaS, the meter could not be used.

3. Tank Material. The tank should transmit ultrasonic signal well, and no air interlayer if the tank wall is multilayer material. Thickness should be 2-70mm. 


How to select?

When you are not very clear about how to select an external level meter model, please kindly use following table.

ProductA+E 69L/
Cintrinsic safe
SystemLtwo wire
Sfour wire
Rangem03, 05, 10, 15, 20, 30, 50 (m)
