Water treatment facilities are located all over the globe, including agricultural water, portable water treatment plants, wastewater treatment plants, industrial water, etc. Ametek Calibration specializes in the manufacture of calibration and test equipment for utilization throughout the water and wastewater industries. From digital test gauges and data recorders, to high accuracy dry block temperature calibrators, they produce a wide range of calibration equipment.

Transmitter/Flow Computer Calibration and Validation
Along with temperature, static and differential pressures are usually measured to calculate flow by employing transmitters and flow computers. Calibration and validation is required to assure their accuracy. The nVision permits a user to complete pressure calibration and validation of a differential transmitter, and Ametek Calibration temperature calibrators calibrate the temperature component, their ASC-400 and CSC201 simulate the signal to the flow computer.
Datalogging/Data Recording
Record current, pressure, voltage and temperature at up to 10 readings per second by using the nVision. The battery-optimizing, Ultra Low Power (ULP) mode, permits a full year of continuous recordings on a set of batteries.
Chart Recorder Replacement
Where ordinary recorders would fail or be inaccurate, data loggers from Ametek Calibration can be employed in wet, remote, hazardous, applications. The nVision is the perfect replacement for aging chart recorders. It provides more accurate readings in a smaller, lighter, and more robust package, while saving data in an electronic format. One 10,000 psi nVision could potentially replace most chart recorders, since chart recorders rarely have resolution which is better than 1 psi.
Transmitter/Flow Computer Calibration and Validation
In addition to temperature, static and differential pressures can be measured to calculate flow by utilizing transmitters and flow computers. To ensure their accuracy, calibration and validation is required. The nVision lets a user complete pressure calibration and validation of a differential transmitter, Ametek Calibrations ASC-400 and CSC201 simulate the signal to the flow computer and their temperature calibrators calibrate the temperature component.
Tank Level (Storage)
The nVision provides a fast and easy way to record accurate pressure measurements, and the RTC measures and calibrates temperature. Producers store their inventory in holding tanks, and an accurate pressure and temperature measurement of each storage vessel creates a record of their inventory on-hand.
Pump Testing
The nVision monitors inlet and outlet pressures and records from two pressure sensors, as fast as 10 times per second, up to 15 000 psi, to characterize the pump.
Relief Valve and Rupture Disc Testing
Pressure safety valves and rupture discs protect pressure vessels and piping systems from excessive internal pressure. Periodic testing and adjustment of this equipment is critical to maintain overall safety. To perform and record the tests Ametek Calibration equipment catches the maximum pressure at high speeds (up to 10 readings per second).
Wellhead Testing
Wellheads provide the pressure interface for both drilling and production equipment offshore. Ametek Calibration supplies accuracy which is unmatched, to test and record pressures on the wellhead up to 15 000 psi / 1000 bar.
Tubing and Casing Pressure Graphing
Operators have to record a well’s casing and tubing pressure simultaneously in order to make appropriate adjustments to wells. By utilizing a reference recorder from Ametek Calibration these tests can be completed on the surface, saving money and time. The nVision can record two pressures simultaneously at up to 10 times per second, and store 500,000 readings.
Filter Testing
By estimating a filter's relative age and wear in this manner, a customer can save money by only replacing filters when needed. The nVision can measure and record differential pressure at high static pressure directly across a filter.
Hydrostatic Testing/Leak Testing
Tanks and pipelines are tested for their strength and leaks by pressurizing a liquid, and seeing whether there is a pressure loss. Both the XP2i and nVision record the pressure test and create a digital record. Pressure and temperature can be recorded simultaneously using the nVision.
Direct Pressure Measurement
Numerous locations throughout water facilities need direct measurement of pressure. This may involve either permanently mounting an instrument or completing periodic checks. The instrumentation from Ametek Calibration gives the flexibility and accuracy to measure pressure correctly.
Barometric Pressure Measurement
Some applications, for example calibrating absolute pressure gauges, will need a reference gauge to read directly in barometric pressure. The nVision and the HPC40 series, with the barometric reference option will indicate pressure in the absolute scale. Toggling between gauge and absolute pressure on the same device is even possible.
General Calibration and Maintenance
Pressure and temperature transmitters, pressure gauges, transducers, electronic sensors, regulators, valves, and pressure and temperature switches have to be checked and calibrated regularly. The nVision provides numerous modules and special test modes for verification that is quick and easy.
Injected Wells
To stimulate production, a pressurized fluid or gas is injected into a well. The wellhead pressure and injection pressure are monitored simultaneously to optimize flow. The nVision can record two pressures simultaneously at up to 10 times per second, and store 500,000 readings.
Deadweight Tester Replacement-Augment
The nVision gives the accuracy of a deadweight tester in a more portable, much lighter package. It is also unaffected by gravity or temperature, needs no special training, and is less expensive to calibrate.
Maintenance of Calibration Standards and Test Equipment
Test equipment and portable calibrators require periodic checks and calibration. Having local standards on site for calibration of these instruments provides savings in cost and downtime of instruments: calibrate the field instruments locally and then only send the standard in for regular calibration. The HPC40 Series and nVision are light-weight, small, instruments that have the accuracy needed to calibrate pressure in the field or in a lab.
The RTC and PTC series are excellent standards for the verification and calibration of handheld thermometers. The DTI Series with an STS may be used as high accuracy temperature references. The AMC-910 offers capabilities for local calibration of electrical signals and with the APM CPF and an STS probe may be used for pressure and temperature calibration.
There is no better pressure standard than a deadweight tester for calibrating pressure instruments and the deadweight testers from Ametek Calibration are designed to be highly accurate but durable.
