2 Appearance and installation
The external structure is shown in Figure 1,plug-inExternal liquid level gaugeThe 316L flexible wire input type is composed of a housing, amplifier, terminal block, protective cap, 316L wire, etc. According to the user's needs, a pointer meter and an intelligent meter head display can be selected.

3 Installation method
⑴ Choose a place that is easy to operate and maintain for installation;
⑵ It should be installed as far away from the vibration source as possible;
⑶ Keep as far away from heat sources as possible;
When installing the immersion type liquid level transmitter, the metal probe should sink to the bottom of the container.

6 Precautions for safe use
(1) When handling and installing transmitters, care should be taken to avoid collisions that may affect the performance of the circuit.
⑵ There is an isolation diaphragm inside the pressure inlet of the transmitter. Do not touch it with foreign objects manually.
Please strictly follow the wiring method for electrical connections,plug-inExternal liquid level gaugeWiring errors can cause damage to the amplifier circuit.
⑷ When installing the immersion type liquid level transmitter, do not use wires to lift heavy objects other than the product.
⑸ Regularly dredge the probe to prevent blockage of the inlet.
The wire is a specially designed waterproof wire. During installation and use, wear, puncture, and scratching of the wire should be avoided. If the above problems exist on site, protective measures should be taken for the wire. If such problems occur and cause malfunctions, the manufacturer will charge for the cost of the wires during repairs.
If you encounter any problems during installation and use, please contact our company. In case of any abnormalities in the product, please do not open it for repair without authorization.
