The Rosemount 1195 Integral Orifice Flow Meter is a high accuracy differential pressure flow meter suitable for measuring any clean gas, liquid, or vapor flow in small line sizes from 1/2 to 1-1/2 inches. Designed with minimal installation and maintenance requirements, the 1195 can be directly mounted to any Rosemount differential pressure transmitter to create a complete flow monitoring system.

The 1195 utilizes a self-centering plate, precision honed pipe section and tight machining tolerances to ensure higher installed performance while eliminating installation errors that are magnified in small lines. The meter is available with a wide range of materials and process connections to suit nearly any application. Accuracy up to ±0.75% of flow rate is achievable.

Maximum temperature range is 450°F in standard direct mount applications, and up to 850°F for remote mount applications with the High Temperature option selected. The integral thermowell enables fully compensated mass flow measurement. The meter produces the most accurate and repeatable measurement when used in single-phase flow or steam flow above the saturation temperature.

Compliant with NACE MR-0175, the 1195 is suitable for demanding applications in the oil and gas, petrochemical, and power industries where small line sizes require high accuracy flow measurement.
