MSP Ultrasonic Level Transmitters
MSP422, MSP400, MSP900 & MSP900SH

The MSP400 and MSP900 family of 2 wire loop powered Ultrasonic level transmitters comprises 4 models:

The entry level transmitter for general purpose level measurement duties. Designed for safe area use with a range of 8m/26ft the MSP422 is easily mounted over a liquid surface using the 2"/25mm threaded process connection. An integral display and 3 push buttons allow fast set-up in less than 2 minutes.

Operating over a range of 11m/36ft, the MSP400 may be locally programmed using the 3 integral push buttons to calculate volume or open channel flow. Two integral relays are provided for local alarm or fault indication. HART compatibility allows remote programming and monitoring.

For use in hazardous areas, the MSP900 is Intrinsically Safe certified. With a 11m/36ft range and HART capability, this transmitter provides an economical solution in level or flow measurement applications.

Specifically designed for use in wet wells and lift stations, this factory sealed transmitter is supplied with 10m/33ft of cable for wiring into the control system. Operating range is 12m/40ft.

Rosemount 3300 Series Guided Wave Radar Level and Interface Ttransmitters - For reliable and accurate level measurement in process tanks, Guided Wave Radar technology is the perfect solution. And the new Rosemount 3300 Series is the perfect choice among Guided Wave Radar (GWR) level transmitters. 

The Rosemount 3300 provides reliable and cost effective measurement in a number of applications where other types of loop-powered transmitters cannot be used. GWR technology combined with advanced signal processing and sensitivity ensures that the Rosemount 3300 Series delivers both level and interface measurement data from the same transmitter.

  • First loop-powered level and interface transmitter.
  • Multivariable™ output from one device reduces process penetrations and installation costs.
  • Direct level measurement means no compensation for changes in temperature, pressure, density, dielectric or conductivity.
  • Virtually unaffected by dust, vapor, interfering obstacles and turbulence. Even suitable for small or odd shaped tanks.
  • Intrinsically safe and Explosion proof makes it suitable for hazardous areas.
  • PC setup software with installation wizard provides easy configuration.
  • Dual compartment transmitter housing (electronics and cabling separated) which can
    be removed without opening the tank, and cut-to-fit probes facilitate easy installation and minimize need for maintenance.
  • Compatible with the Asset Management Solutions™ (AMS) plant management
    software - cuts costs by streamlining maintenance tasks.

Applications for the Rosemount 3300 Series Transmitters 
Rosemount 3300 Series can be used for level measurements on most liquids, semi-liquids and liquid/liquid interfaces in any of the following industries: 

  • Chemical and petrochemical industry
  • Oil and gas industry
  • Pulp and paper industry
  • Pharmaceutical plants
  • Food and beverage industry
  • Water and sewage treatment
  • Hydroelectric dams and power plants
