Lakes Product overviewPCM266 Smart Submersible Level Transmitter
accurately measures static pressure of the liquid proportional to
the level depth using high performancepiezoresistive diffused
silicon pressure sensor as the measuring element. The result is
converted to standard current or voltage signal output
throughsignal conditioning circuit, establishing the linear
corresponding relation between the output signal and liquid depth
to complete the measurement of theliquid depth. The product has
advantages of high precision and small volume. Submerse it
directly into liquid, the height between the end of the
transmitterto the liquid surface is measured easily. The
product is applicable to the measurement and control of the liquid
level in the petroleum, chemical industry, powerplant, urban water
supply and hydrological exploration fields. Product

Product selection and installation instructions
(for reference
only) 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 cableconnecting 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 bottomof 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 innerdiameterof about 5cm.
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 fixthe 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 theadverse effects of dynamic
pressure and wave and ensure the measurement accuracy.
