PCM266 level transmitter is a fully sealed submerged type liquid level measuring instrument in full stainless steel design. The product adopts high stability and reliability piezoresistive OEM pressure sensor and high precision smart transmitter processing circuit, and applies precision digital temperature compensation technique and non-linearity correction technique. The waterproof cable is hermetically connected to the shell, and the breather pipe is set inside the cable, which can be used in liquid for a long time. The integrated structure and standardized output signal provide convenience for field use and automatic control. The product works in two wire system. It is compact, light-weighted, easy to install and use. It can directly replace the analog output transmitter of 4 ~ 20mA of two wire system. It is applicable to equipment matching and the measurement and control of static pressure level and liquid level in liquid tanks, sewages, industrial water, ponds, wells, rivers, sea, lakes, etc.

Installation instructions (for reference only)
|
1. Installation in still water (deep wells, pools, liquid tanks, etc.)
Installation tips:
1) When measuring the level of stationary fluid in an open container, place the level transmitter vertically into the bottom of the container and secure the cable connecting the transmitter to the junction box at the opening of the container.
2) When the medium viscosity is relatively large (such as sewage pool), casing or bracket can be installed to ensure that the transmitter can be put into the bottom of the container.
3) When doing an open-air installation, the terminal box of the transmitter should be placed in a ventilated and dry place to avoid direct exposure to light and rain, which may cause the shell temperature to be too high or water to get inside and damage the internal circuit board.
2. Installation in moving water (rivers, lakes, etc.)
Installation tips:
1) When measuring the water level in flowing water, when the medium fluctuates greatly, a steel pipe can be inserted in the water channel with an inner diameter of about 50 cm. Make several holes of about Φ5 in diameter on the side of the immersed pipe opposite to the flow direction to allow water to enter the pipe and fix the cable and junction box at the outlet of the pipe.
2) When the medium of the water channel fluctuates greatly or the sediment is large, a damping device can be installed to filter the sediment, eliminate the adverse effects of dynamic pressure and wave and ensure the measurement accuracy.
3) When installing the product in lightening intensified area, please indicate "Lightning Protection" when placing an order. Meanwhile, it is recommended that users install lightning protection devices at the site and ensure that the product and power supply are reliably grounded to reduce damage to the transmitter caused by lightning.
