Importance of Cost Savings

In the manufacturing industry, prioritizing cost savings is crucial for both smaller and larger companies undertaking projects without the burden of overpriced instruments. Utilizing pressure sensors, a traditional yet effective method involves measuring liquid levels in a tank by assessing the water column. Even for non-water liquids, these sensors prove effective when an intelligent correction factor for density and liquid type is applied.

Configuration for Efficient Level Indication

Our team has successfully configured pressure sensors for level indication in the Philippines, offering significant savings in both cost and time for tank fabricators. These reliable level measurement devices help prevent overspill, empty tanks, and ensure basic control of the final liquid product.

User Familiarity and Installation Points

Once users acquaint themselves with pressure sensors for level measurement, selecting the appropriate installation point for the sensor becomes a straightforward process.

Revisiting Traditional Methods

Amidst the influx of newer technologies, it’s essential to remember the reliability of traditional methods. Measuring pressure exerted by a volume of liquid at the tank or well’s bottom proves sufficient, especially for non-critical applications. Standard pressure sensors can be converted into level-based transmitters by considering factors such as tank type, size, and liquid specific gravity.

Temperature Compensation for Accuracy

Built-in temperature compensation for the pressure transmitter ensures accurate measurements across different temperatures. These sensors are suitable for non-pressurized tanks, meeting accuracy, stability, and repeatability requirements. The technology’s simplicity allows for the pre-configuration and cost-effective installation of a level sensor using a pressure reading transmitter within a short period.

Enhancing Compatibility & Versatile Connection Options

Correctly specified connections pose no issues, whether installing in NPT, BSP, or sanitary type connections using a Tri-Clamp.

In all technologies, there are advantages and disadvantages. However, using pressure-based level sensors correctly minimizes issues like foam build-up, vapors, and physical objects in the tank. This is because we are measuring “pressure,” directly correlated to a level measurement using a calibration method for zero and span.

In the case of pressurized tanks, the level sensor remains an option but requires careful consideration, as it might be necessary to measure the differential pressure from certain points.
