Description:

The Rosemount 3100 Series ultrasonic level transmitter is a liquid level transmitter based on ultrasonic technology that is suitable for many liquid applications. The Rosemount 3100 Series ultrasonic level transmitter is simple to set-up and operate. Once installed, maintenance is minimal. Non-contacting measurement with no moving parts eliminates the problems typically experienced with contacting instrumentation. The Rosemount 3100 Series ultrasonic level transmitter features 2 integral signal relays, corrosion resistant PVDF wetted material, simple push button programming, automatic temperature compensation, and a built-in LCD display.

The entry-level Rosemount 3101 ultrasonic level transmitter is designed for simple level or distance measurements over a range of 1 to 26 ft and a 4-20mA signal output.

The Rosemount 3102 ultrasonic level transmitter has two integral relays for level or distance measurements over a range of 1 to 36 ft. It also features volume and open channel flow calculations and a 4-20mA / HART output.

The Rosemount 3105 ultrasonic level transmitter is intrinsically safe for use in hazardous areas. HART digital communications are also provided. With a PVDF wetside, the Rosemount 3105 ultrasonic level transmitter can be used in most hazardous and corrosive applications. Apart from the integral temperature sensor, an optional external temperature sensor may be used with the Rosemount 3102 and 3105 ultrasonic level transmitters, which may be used to measure distance and level or calculate volume or flow in an open channel.

Applications:

The Rosemount 3100 Series is a liquid level transmitter based on
ultrasonic technology that is suitable for many liquid applications.
Ultrasonic pulse signals are transmitted and reflected from the
liquid surface. The transmitter ‘listens’ for reflected signals
(echoes) and measures the time-delay between transmitting and
receiving.
The distance to the liquid surface is automatically calculated using
the computed time-delay.
An integral temperature sensor continuously measures the air
temperature around the transmitter. It then computes the speed of
sound in air, automatically compensating the Distance for
temperature effects. The 3102 and 3105 have a Remote
Temperature Sensor option.
The distance measurement can be sent through the 4–20 mA or
HART® output.

Competitive Advantage:

Advanced Software Features
• Learn routine (false echo registration)
The transmitter can learn to ignore up to four false echoes,
caused by the pulse signal reflecting off obstructions, until
the actual level is seen.
• Empty tank mapping
When a tank is empty, the transmitter can learn to ignore up
to four false echoes, without the need for user interaction.
• Present depth
The bottom reference can be automatically set using a
known user-entered depth.
• Set as empty
When the tank is empty, the bottom reference can be
automatically reset to the measured distance.
• Distance offset
The distance to the surface can be adjusted by a
user-entered positive or negative offset value.
• Level offset
The level can be adjusted by a user-entered positive or
negative offset value.
• Bottom blanking
The transmitter can be set to ignore an area of the tank
bottom to avoid false echoes from obstructions.
