5. Measurement Method
It is based on fluorescent optical technology.
A fluorometer generates the wavelength of light required to excite the analyte of interest, it selectively
transmits the wavelength of light emitted, then it measures the intensity of the emitted light. The emitted light is
proportional to the concentration of the analyte being measured.

Chapter2. Installation

1. Pre-requirement:
Please provide sufficient cover for the transmitter’s signal line and avoid the signal line being
tied together with the power line.
SMR35 turbidity transmitter is a delicate digital RS 485 transmitter, suitable to a wide range of
water and wastewater applications.

2. Installation:

1.1. Fix the holder of SMR35 (turbidity transmitter) onto the lid of the tank, and
soak the transmitter into the water to be measures, then link the transmitter with
holder to complete the installation.

1.2. Put two layers of the isolate plates to prevent the bubbles from affecting
the numerical stability of turbidity.

with that of SMR35 transmitter. Please use AQSMR to check SMR35’s parameters in advance.
(b) Check whether the transmitters connected to the system have repeated ID(s) or not.
(c) Make sure the power source is 5 V.
(d) Make sure all the connectors are well connected.
2.2. Unstable Readings:
(a) Clean the optical glass.
(b) Check if there are bubbles on the surface of glass.
2.3. Frozen Readings:
(a) Make sure the connectors of SMR35 transmitter are well connected.
2.4. Inaccurate Measured Values:
(a) Clean and surface of optical glass.
(b) Re-calibration
