Emerson Rosemount Clarity II T56, Reference Manual

Page: 7 / 60

1 Description and specifications
1.1 Features and applications
The Rosemount T56 turbidmeter is intended for the determination of turbidity in water.
Low stray light, high stability, efficient bubble rejection, and a display resolution of 0.001
NTU make the turbidmeter ideal for monitoring the turbidity of filtered drinking water.
You can also use the turbidmeter in applications other than drinking water treatment.
Examples are monitoring wastewater discharges, condensate returns, and clarifiers.
Currently, new ISO 7027 systems are available, with replacement EPA 180.1 sensors
available for current install base. USEPA 180.1 sensors use a visible light source. ISO 7027
sensors use a near infrared light emitting diode (LED). For regulatory monitoring in the
United States, you must use USEPA 180.1 sensors. Regulatory agencies in other countries
may have different requirements.
The turbidmeter consists of a transmitter, which accepts either one or two sensors, the
sensors themselves, and a debubbler/measuring chamber and cable for each sensor. The
cable plugs into the sensor and the transmitter, making setup fast and easy. Sensors can
be located as far as 50 ft. (15.2 m) away from the transmitter.
The turbidmeter incorporates the popular and easy to use Rosemount 1056 transmitter.
Menu flows and prompts are so intuitive that you practically do not need a manual. Analog
outputs are fully scalable. Alarms are fully programmable for high/low logic and dead
band. To simplify programming, the transmitter automatically detects whether an EPA
180.1 or ISO 7027 sensor is being used.
The turbidmeter is available in an optional configuration in which the transmitter,
sensor(s), and debubbling flow cell(s) are mounted on a single back plate. The sensor
cables are pre-wired to the transmitter, so setup is exceptionally fast and easy. Simply
mount the unit on a wall, bring in power and sample, and provide a drain. To order this
option, consult the factory.
