Product Description
1. Description
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.
The transmitter then calculates the liquid depth (level) and outputs the level as a 4–20 mA signal (and a digital HART® signal on the Rosemount 3102 and 3105). The Rosemount 3102 is used for measuring the level only.
The Rosemount 3102 and 3105 can calculate distance-to-surface, contents (volume), or open channel flow, and then output the result as a 4–20 mA signal and a digital HART signal.
An integral temperature sensor continuously measures the air temperature around the transmitter. It then computes the speed of sound in air, automatically compensating the calculated distance for temperature effects. The Rosemount 3102 and 3105 have a remote temperature sensor option.

RIA15 process indicator The process indicator is available with 4 to 20 mA or with HART® protocol. In the HART® version up to 4 measured values of one sensor can be indicated in alternation. For this, the indicator can be set as a primary or secondary HART® master and actively inquire the values from the sensor. The small voltage drop of < 1V (< 1.9 V with HART®) is a huge advantage, especially in Ex-applications, where in most cases only a reduced voltage is available.
Flowserve Pneumatic Actuators - Linear - VL Series VL25 Valtek
VL Actuator Valtek VL series spring cylinder linear actuators are powerful, compact, high-performance pneumatic actuators that provide solid throttling or on-off operation for automatic control valves. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response and quick stroke speeds.
