The Micro Motion H150S is the industry-leading 316L Stainless Steel sensor designed for the most demanding sanitary environments. Unlike standard meters, this 1.5-inch DN40 model provides exceptional liquid mass accuracy and volume flow repeatability, ensuring your product consistency remains unmatched in precision-driven production lines.
The H150S is engineered with a compact, drainable design, making it the perfect fit for CIP and SIP cycles. The standard 32 Ra (0.8 μm) internal finish prevents bacterial growth and biofilm accumulation, a critical requirement for dairy and brewery applications.
With a sensor maximum working pressure of 1,450 psig (100 barg), the H150S offers a robust measurement solution for high-pressure hygienic processes. Whether you are managing batching and loading or monitoring density measurement in real-time, this meter delivers fast product change-over and reduced waste.
Gain measurement integrity assurance without stopping your flow. The integrated Smart Meter Verification (SMV) audits the sensor health and electronics in under 90 seconds, providing the documentation needed for legal metrology and quality audits.
Equipped with Emerson’s MVD (Multivariable Digital) technology, the H150S offers the highest immunity to external vibration and process noise. It excels in "slug flow" or two-phase applications where entrained air often causes lesser meters to fail.

Viscosity Profile: For high-viscosity fluids like syrups or chocolate, ensure the DN40 size meets your pressure drop requirements.
Accuracy Grade: Choose the optional high-accuracy (±0.10%) package for custody transfer approvals or high-value ingredient dosing.
Housing: Specify the all-stainless steel housing if the meter is located in a high-corrosion washdown area.
Orientation for Drainage: To achieve the best self-draining performance, install the sensor vertically with flow moving upward. If horizontal installation is required, ensure the tubes are positioned to allow gravity drainage.
Process Stress: Avoid mechanical stress on the sensor. Ensure the pipeline is correctly aligned before tightening flanges or Tri-Clamps to prevent zero-point drift.
Zero Calibration: Perform a zero-check during commissioning when the meter is full of process fluid at zero flow.
On-board Historian: Utilize the internal historian to track process upsets or cleaning cycle temperatures to optimize your maintenance intervals.
Q1: What does the 15 Ra finish mean for my process? A: A 15 Ra (0.4 μm) finish means the internal surface is polished to an extreme smoothness, preventing bacteria from "hiding" in surface microscopic cracks. This is essential for EHEDG and 3-A compliance in food and pharma industries.
Q2: Can it handle entrained air during batching? A: Yes. The H150F features advanced multivariable digital technology that maintains measurement stability during two-phase flow conditions, often seen in loading/unloading or aerated fluid applications.
Q3: Is the H150F self-draining? A: Absolutely. The sensor is designed with a specific geometry that allows for complete self-drainage when installed in the correct orientation, which is vital for effective CIP/SIP cycles.
