Measure Engineering maintains four NIST traceable primary liquid flow calibration systems utilizing water as the calibration medium. Each system uses a high accuracy Coriolis meter as a secondary standard and its own gravimetric time-mass system as a primary standard. These four systems cover overlapping ranges so that they may be checked against each other.

LIQUID PRIMARY A (WEIGHT MATHOD)

The system's flow rate range is 1.0 to 20.0 kg/m. (60.0 to 1200.0 kg/hr.).The best measurement capability is 0.06% of reading.

LIQUID PRIMARY B

The system's flow rate range is 20.0 to 250.0 kg/m. (1,200 to 15,000 kg/hr.).The best measurement capability is 0.06% of reading.

LIQUID PRIMARY C

The system's flow rate range is 35.0 to 650.0 kg/m, (1,800 to 40,000 kg/hr.). The best measurement capability is 0.06% of reading.

LIQUID PRIMARY D

The system's flow rate range is 100 to 1700 kg/m. (6,000 to 102,000 kg/hr.).The best measurement capability is 0.10% of reading.

ROTAMETER CALIBRATION IN LIQUIDS AND GASES

Rotameters are a gauge that consists of a graduated glass tube containing a free float for measuring the flow of a fluid or gas. Usually a rotameter will have a tube that holds a pellet or cylinder that will move up the scale according to the pressure from the gases or liquids it is measuring.

Slotted Tube Rotameters - This unit uses a slotted cylinder and piston rather than a tapered tube. This piston portion of the meter float travels within the cylinder, the piston acting as the fourth side of the slot. As with standard tapered tube meters, the fluid flow raises the piston until sufficient slot area is exposed to bring about your final measurement.

Vane type Rotameters and Piston type Rotameters - Another type of flow meter that has a tapered interior chamber that allows a fitted piece to raise or lower into the unit to measure flow.

During its use, a rotameter will accumulate foreign material inside and will eventually lose its sensitivity to measurement. In many cases, a yearly rotameter calibration will keep your measurements accurate and save you time and money in maintenance. Measure Engineering's, calibration plant has calibrated Rotameters from dozens of manufacturers, and we have established yearly rotameter calibration schedules with many of our clients. Listed below are several that we have calibrated to NIST accuracy and ISO 17025 (Future soon)

Worldwide Batch Controller

OMNI Flow computer support for flow rate computing, totalize, and calculation We can use analogue, frequency, or pulses direct to batch controller and computing to flow rate. And results of calibrated will energize by OMNI flow computer are not print by pen.

There are times when it's not practical to carry out control valve overhaul on site, it can be that specific specialist hydro testing or specialist repairs to control components are required to carry out the inspection / overhaul / servicing of a control valve off site, it may simply be more economical to remove equipment from site.
