Water treatment facilities are found worldwide, including potable water treatment plants, wastewater treatment plants, agricultural water, industrial water, etc. We specialize in producing calibration and test equipment for use throughout the Water and Wastewater Industries. From digital test gauges and data recorders, to high accuracy dry block temperature calibrators, we have a variety of equipment to help you do your job.
Chart Recorder Replacement – Our data loggers can be used in wet, hazardous, and remote applications, where ordinary recorders would fail of be inaccurate. The nVision is an excellent replacement for aging chart recorders. It offers higher accuracy in a smaller, lighter, and more robust package, while saving data in an electronic format. It has been suggested that one 10 000 psi nVision could replace most chart recorders, since chart recorders rarely have better than 1 psi resolution.

Tank Level (Storage) – 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. The nVision offers an easy and fast way to record accurate pressure measurements, and the RTC measures and calibrates temperature.

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 essential to maintain overall safety. Our equipment catches the maximum pressure at high speeds (up to 10 readings per second) to complete and document the tests.

Filter Testing – The nVision can measure and record differential pressure at high static pressure directly across a filter. By estimating a filter's relative age and wear in this manner, a customer can save money by only replacing filters when needed.

Transmitter/Flow Computer Calibration and Validation – Static and differential pressures, along with temperature are commonly measured to calculate flow, using transmitters and flow computers. Calibration and validation is needed to assure their accuracy. The nVision allows a user to complete pressure calibration and validation of a differential transmitter, our temperature calibrators calibrate the temperature component, and our ASC-400 simulates the signal to the flow computer.

Datalogging/Data Recording – Record pressure, temperature, current, and voltage at up to 10 readings per second using the nVision. The battery-optimizing, Ultra Low Power (ULP) mode, allows an entire year of continuous recordings on one set of batteries.

Hydrostatic Testing/Leak Testing – Pipelines and tanks are tested for their strength and leaks by pressurizing a liquid, and observing whether there is a pressure loss. Both the XP2i and nVision record the pressure test producing a digital record. Pressure and temperature can be recorded simultaneously by using the nVision.

Wellhead Testing – Wellheads provide the pressure interface for both drilling and production equipment offshore. We provide unmatched accuracy to test and record pressures on the wellhead up to 15 000 psi / 1000 bar.

Tubing and Casing Pressure Graphing – To make appropriate adjustments to wells, operators must record a well’s casing and tubing pressure simultaneously. Using our reference recorder, these tests can be completed on the surface, saving both money and time. The nVision can record two pressures simultaneously at up to 10 times per second, and store 500,000 readings.
nVision
Injected Wells – A pressurized fluid or gas is injected into a well to stimulate production. Operators monitor wellhead pressure and injection pressure simultaneously to optimize flow. The nVision can record two pressures simultaneously at up to 10 times per second, and store 500,000 readings.

General Calibration and Maintenance – Pressure gauges, pressure and temperature transmitters, transducers, electronic sensors, valves, regulators, and pressure and temperature switches need to be checked and calibrated periodically. The nVision offers multiple modules and special test modes for quick, easy verification.

Deadweight Tester Replacement-Augment – The nVision offers the accuracy of a deadweight tester in a much lighter and more portable package. It is also unaffected by temperature or gravity, requires no special training, and is less expensive to calibrate.

Direct Pressure Measurement – Various places throughout water facilities will require direct measurement of pressure. This could involve permanently mounting an instrument or completed periodic checks. Our instrumentation provides the flexibility and accuracy to confidently measure pressure.

Barometric Pressure Measurement – Some applications, such as calibrating absolute pressure gauges, will require the reference gauge to read directly in barometric pressure. The nVision and the HPC40 series, with the optional barometric reference will indicate pressure in the absolute scale. You can even toggle between gauge and absolute pressure on the same device.

Maintenance of Calibration Standards and Test Equipment - Portable calibrators and test equipment requires periodic checks and calibration. Having local standards on site for calibration of these instruments offers a savings in cost and downtime of instruments: calibrate the field instruments locally and then send only the standard in for regular calibration. The nVision and HPC40 Series are small, light-weight instruments that have the accuracy required to calibrate pressure in the field or in a lab. The DTI Series with an STS may be used as high accuracy temperature references. The RTC and PTC series are excellent standards for the verification and calibration of handheld thermometers. There is no better pressure standard than a deadweight tester for calibrating pressure instruments and our deadweight testers are designed to be highly accurate but durable.
