With over 5 million transmitters installed worldwide, the 1151 continues to offer industry leading value. Changing customer needs and new technologies have driven product improvements, while advanced manufacturing and testing processes have guaranteed product quality. Even today, the 1151 is world-renowned for proven field reliability and longevity.

Proven field performance and reliability
For over 30 years, the 1151 has provided the process control industry with unsurpasses service and reliability in even the harshest of environments.The lasting customer preference results from a combination of advanced technology, and a tradition of field proven performance.

Commitment to continuous improvement
Through ongoing focus on continuous improvement, ±0.075% reference accuracy has been accomplished as a result of manufacturin gand engineering enhancements. In addition, Smart electronics offer rangeability to 50:1, reducing the number of transmitters to specify, procure, and carry in inventory. A modular design allows interchangeable mechanical and electrical components, providing backward and forward compatibility.

Application flexibility
The 1151 offers a variety of configurations for differential, gage, absolute and liquid-level measurements including integrated solutions for pressure, level, and flow. High pressure models allow static line pressures up to 4500 psi (310 bar).

Multiple wetted materials, as well as alternative fill fluids ensure process compaitbility. Smart, analog and low-power electronics are available to meet specific application requirements.

Pressure Solutions

3051S Series of Instrumentation
Scalable pressure, flow and level measurement solutions improve installation and maintenance practices.

Mass Flow Transmitter
Accurately measures differential pressure, static pressure and process temperature to dynamically calculate fully compensated mass flow

Integral Manifolds
Factory-assembled, calibrated and seal-tested manifolds reduce on-site installation costs.

Diaphragm Seals
Provide reliable, remote measurements of process pressure and protects the transmitter from hot, corrosive, or viscous fluids.

Orifice Plate Primary Element Systems: Orifice Plates, Flange Unions, and Meter Sections
A comprehensive offering of orifice plates, flange unions and meter sections that is easy to specify and order. The Conditioning Orifice provides superior performance in tight fit applications.

Annubar Flowmeter Series
The state-of-the-art, fifth generation Annubar combined with a MultiVariable transmitter creates an accurate, repeatable and dependable insertion-type flowmeter.

Compact Orifice Flowmeter Series
Compact Orifice Flowmeters can be installed between existing flanges, up to a Class 600 (PN100) rating. In tight fit applications, a conditioning orifice plate version is available, requiring only two diameters of straight run upstream.

ProPlate Flowmeter Series
These integral orifice flowmeters eliminate the inaccuracies that become more pronounced in small orifice line installation. The completely assembled, ready to install flowmeters reduce cost and simplify installation.
