Water Industry Overview - .PDF file.

Ashcroft offers a variety of pressure, temperature and control instruments specifically designed to meet the demands of the water treatment and wastewater industries.

In addition, the company provides detailed documentation to meet critical engineering and compliance requirements.

Ashcroft’s dry, liquid-filled and Plus Performance pressure gauges are designed to meet the rigors of water treatment and wastewater applications.

Its Duragauge process gauges are used when a solid-front, ASME-grade 2A, 1/2 per cent accuracy pressure gauge is required.

Standard features include a 400 Series stainless steel movement to provide longer life, an epoxy-coated system to ensure corrosion resistance and the patented Duratube Bourdon tube to provide strength.

When pulsation and vibration are present in the process, the patented Plus Performance option provides the performance of a liquid-filled gauge, all in a dry gauge.

Plus Performance dampens vibration and pulsation, providing an easy-to-read gauge with no fill lines and a steady pointer.

Plus Performance provides a wider temperature range over glycerin fill and eliminates costly speciality fluids, as well as the added expense for disposing of a liquid-filled gauge.

Stainless steel case gauges are offered with a rugged, all-welded, socket-to-case design.

When vibration and pulsation are a factor, these gauges are also available with the patented Plus Performance option as well as the patented Powerflex movement for improved shock resistance.

Independent laboratory testing has shown that the Powerflex movement is more shock resistant than conventional movement gauges.

When a low-cost, commercial-type gauge with bronze wetted parts is a requirement, Ashcroft commercial gauges are available with the Powerflex movement as well as true-zero indication.

With true-zero indication, users can be certain that if their gauge reads zero, there truly is zero pressure in their system.

Designed to measure the difference between two pressures across filters, strainers or separators, Ashcroft differential-pressure gauges offer a combination of Bourdon tube design and flexible diaphragm designs.

Together, these features enable users to measure differential pressure in critical applications.

Ashcroft Instruments

Over 150 years ago, Edward Ashcroft saw the need for safer, more sophisticated pressure and temperature instruments for use in the emerging steam industry. In response, he introduced a then-revolutionary new Bourdon tube pressure gauge. The rest is history.

Times continue to change and so do the needs of industry. Products manufactured by Ashcroft Inc. have become the benchmark in pressure and temperature measurement and include gauges, thermometers, switches, transducers, transmitters, instrument isolators and diaphragm seals and control and calibration equipment.

Specified around the world for the most demanding requirements, these instruments are widely recognized under the brand names Ashcroft, Heise, Willy, and Weksler. And you can find them in wastewater treatment facilities, biotech and pharmaceutical labs, medical applications, semiconductor facilities, refineries, power generation plants, food processing plants, pulp and paper mills, chemical manufacturing plants and the host of support companies that serve these industries.

Our team consists of experts ready to help resolve even the most difficult applications and technical issues. If you require broader specifications than our standard product line offers, our engineers, technical staff and product marketing specialists can work with you to custom fit the right product to the job. Our customer service representatives are highly trained to answer product application questions, offer competitive product cross-references and work closely with you to help meet your goals.

We maintain an extensive network of field and in-house sales personnel, local representatives and distributors to ensure you receive quick product delivery and service. Along with our “partner” representatives we offer product training and education, facility surveys, calibration services, seal assembly and answers to your application questions.  

Safety is a critical issue, and our instrument audit can improve the safety or your plant. Industry surveys indicate that 20% to 30% of customers’ instruments are misapplied and fail prematurely due to pulsation and vibration, allowing the process media or liquid fill to escape and cause environmental damage or even harm those nearby. Experts from Ashcroft Inc. can help identify areas of concern before they become problems. This important service will help prevent accidents, avoid misapplications and save money and time.  

As the leader in technology and innovation we design new products based on current and emerging market requirements as well as individual customer’s requirements. As the industry leader our “firsts” lead the way with breakthrough new product features and value added benefits for the customer. With our 2005 acquisition by (our longtime sensor partner) Nagano Keiki Company of Japan we now have access to additional engineering expertise and superior, exclusive sensor technology.
