7230 HT Series Multi-Variable Level Sensor for Level, Interface and Temperature Measurements



Field-Proven System Provides Ideal Solution for Difficult "Mixed" Hydrocarbon and other Oil & Gas Applications.

CLAWSON, MI - At the heart of the new high-accuracy, level measurement system from AMETEK Automation & Process Technologies, is the 7230 Series HT Digital Probe--a versatile, multi-variable level sensor that provides total level, interface level and up to 5 temperature readings and a diagnostic function.

The 7230 HT Series Digital Level Sensor was specifically designed to provide a single sensor for the measurement of multiple layers of oil products and gas condensates, including water layers, making it ideal for oil and gas pipeline applications. The sensor requires no calibration and only one process connection. It provides the highest level of accuracy available for materials that are difficult to measure using most other level technologies. These include mixed hydrocarbons and other low dielectric liquids.

The 7230 HT Series utilizes field-proven magnetostrictive position sensing technology in a unique design that makes it more reliable and easier to install and maintain. The probe's accuracy is an impressive 0.01% of measured span. A patented reflector increases signal resolution and repeatability to 0.0001 inch.

The probe's performance is unaffected by changes in the process material's electrical characteristics or densities. Hydrocarbon-based condensates have a predictable range of specific gravities that are well within the range of the sensor's standard floats. The probe and floats are made from 316 Stainless Steel and easily mount in a two-inch NPT process connection, using either a flange or adapter bushing. The sensor has an explosion-proof approval rating from FM and CSA for Class1, Div 1, Group A, B, C, D hazardous locations.

A choice of two communications protocols is available. The 7231's standard protocol is Modbus RTU and is also available with an optional Modbus to Analog output converter. The 7235 provides a proprietary ASCII digital output suitable for OEM and wireless applications. Product differentiators, such as multi-variable output, no calibration, minimal maintenance and very high accuracy, distinguish the 7230 Series from non-contact and guided wave radar level sensors that are commonly used for petroleum applications,.

AMETEK Automation & Process Technologies is a unit of AMETEK, Inc. and a leader in level-measurement instrumentation. AMETEK, Inc. is a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of more than $1.8 billion.
