Product Description

Product Description

Rosemounte 3700

In the highly competitive landscape of industrial instrumentation, Emerson's Rosemounte brand has long been recognized as a paragon of innovation and reliability. The Rosemounte 3700, in particular, has emerged as a game - changing product in various industrial applications. 
The Rosemounte 3700 is a state - of - the - art device designed to meet the stringent demands of industrial measurement and control. It belongs to a family of products that have been engineered with precision and expertise, leveraging Emerson's vast experience in the field of process management. Whether it is used in measuring flow, level, or other critical process variables, the Rosemounte 3700 offers unparalleled performance.
The Rosemounte 3700 can accurately measure mass and volume flow rates. For mass flow measurement, it can handle a wide range of flow values, depending on the specific sensor configuration. In applications where high - precision mass flow measurement is crucial, such as in the chemical industry during the dosing of reactants, the Rosemounte 3700 can achieve accuracies of up to ±0.1% of reading.
In terms of volume flow measurement, it is compatible with different types of fluids, including liquids, gases, and slurries. The device can measure volume flow rates with an accuracy that is typically within ±0.2% of the calibrated span. This makes it suitable for applications in the oil and gas industry, where accurate volume flow measurement is essential for custody transfer operations.

1. Technical Specifications

1.1 Measurement Capabilities
Flow Measurement:The Rosemounte 3700 can accurately measure mass and volume flow rates. For mass flow measurement, it can handle a wide range of flow values, depending on the specific sensor configuration. In applications where high - precision mass flow measurement is crucial, such as in the chemical industry during the dosing of reactants, the Rosemounte 3700 can achieve accuracies of up to ±0.1% of reading.
In terms of volume flow measurement, it is compatible with different types of fluids, including liquids, gases, and slurries. The device can measure volume flow rates with an accuracy that is typically within ±0.2% of the calibrated span. This makes it suitable for applications in the oil and gas industry, where accurate volume flow measurement is essential for custody transfer operations.
1.2 Sensor Compatibility
Coriolis Sensors: The Rosemounte 3700 is commonly paired with Coriolis sensors, which are known for their high - accuracy mass flow measurement capabilities. These sensors work on the principle of the Coriolis effect, where the mass flow rate of a fluid through a vibrating tube causes a measurable deflection. The Rosemounte 3700 is designed to interface seamlessly with different models of Coriolis sensors, providing accurate compensation for factors such as temperature, pressure, and fluid density.
1.3 Communication Protocols
HART Communication: One of the key communication features of the Rosemounte 3700 is its support for the HART (Highway Addressable Remote Transducer) protocol. HART allows for two - way communication between the device and a host system, such as a distributed control system (DCS) or a programmable logic controller (PLC). Through HART, operators can remotely configure the Rosemounte 3700, set measurement ranges, and retrieve diagnostic information. This not only simplifies the installation and commissioning process but also enables efficient maintenance and troubleshooting.
WirelessHART: In addition to HART, some models of the Rosemounte 3700 support WirelessHART. This wireless communication protocol offers the advantage of reduced wiring costs and increased flexibility in installation. 

2. Design and Construction

2.1 Housing
Robust and Durable: The Rosemounte 3700 is housed in a rugged enclosure that is designed to withstand harsh industrial environments. The housing is typically made of high - quality materials, such as stainless steel or corrosion - resistant plastics. In industries where the device may be exposed to chemicals, extreme temperatures, or mechanical stress, the robust housing of the Rosemounte 3700 ensures its long - term reliability.
IP Rating: The housing of the Rosemounte 3700 has a high IP (Ingress Protection) rating. Depending on the model, it can have an IP65 or IP67 rating. An IP65 rating means that the device is dust - tight and protected against water jets from any direction, while an IP67 rating indicates that it is dust - tight and can be submerged in water up to a certain depth (usually 1 meter) for a specified period (30 minutes). 
2.2 Display and User Interface
Multi - Line LCD Panel: The Rosemounte 3700 is equipped with a multi - line LCD panel that provides clear and easy - to - read information. The display shows the measured values, such as flow rate, level, or density, as well as other important parameters like units of measurement, status indicators, and diagnostic messages. The backlit LCD, with a resolution of 128 × 128 pixels and a bit - map display, ensures that the information is visible even in low - light conditions. 
Large Push Buttons and Function Keys: To facilitate user interaction, the Rosemounte 3700 has large push buttons with tactile feedback. These buttons are easy to press, even when wearing gloves, which is common in industrial settings. 
2.3 Wiring and Connectivity
Terminal Blocks: The Rosemounte 3700 features terminal blocks for easy wiring of the sensor inputs, power supply, and communication lines. The terminal blocks are clearly labeled, reducing the risk of miswiring during installation. They can accommodate different wire gauges, typically in the range of 0.5 - 2.5 mm², providing flexibility in cable selection. The wiring connections are designed to be secure, ensuring reliable signal transmission and power supply.
Connectors: In addition to terminal blocks, the Rosemounte 3700 may also use connectors for some applications, especially in cases where quick - disconnect or modular connections are required.
