Submersible Level Transmitters

AMETEK’s Submersible Level Transmitters are one of the most complete lines in the industry for measuring industrial and water/wastewater plant level. From the low cost Model SDT with a light weight 316 Stainless Steel body that can measures levels up to 345 feet, to the Model 575 and 675 with a 316 Stainless Steel body and Hastelloy diaphragm that can measure up to 690 feet with CSA intrinsically safe approval for hazardous locations, such as lift stations, process sludge tanks, AMETEK offers a series of different products to meet your level needs.

Level and Pressure Instrumentation for Pulp & Paper Production

Pulp and paper
Pulp and paper applications create a notoriously harsh, high moisture and chemical-laden environment; coupled with extreme vibration in many of the processes. The following document outlines an array of level, pressure, and position applications and solutions for the pulp & paper industry.

Drexelbrook’s ThePoint™ Series Point Level Switch: Settings, Adjustments, and Changing Calibration Modes

The AMETEK Drexelbrook ThePoint™ Series uses No-Cal™ technology to detect the presence or absence of material without calibration or initiation via setpoint adjustments, push-buttons or magnets.

ThePoint™ level measurement switch features both Auto-Cal and manual calibration. The standard Auto-Calibration mode is applicable to most liquid and slurry point level measurements. If preferred, the manual calibration can be used and is recommended for some application. ThePoint electronic unit has auto and manual calibration modes built into the standard unit and can be accessed through the simple routine shown in the video below. The inclusion of these calibration modes allows the Drexelbrook RF Point Level Products application flexibility that is far greater than any other point level product on the market. ThePoint™ level switch can be used in Liquids, Solids, Slurries, and Interface applications.

To learn more specific instructions on the (8) calibration modes ThePoint™ has available, download the "Drexelbrook ThePoint Series Point Level Switch Installation and Operating Instructions" from this link.

Top 5 Considerations in Selecting Pressure Gauges

Pressure gauges are ubiquitous in industry and installed on machinery around the world. While there are millions of possible combinations of shapes, sizes, options and materials, careful attention needs to be given to the following five criteria for safe use and long product life.

1) Process Media
Direct exposure of the sensing element to the process media is a possibility, so attention must be given to any corrosive media, media with particulate, or media that can solidify and clog the pressure gauge element. For non-clogging media, a direct connection and Bourdon tube sensor can be applied. For process media that could potentially cause clogging, a diaphragm seal should be used.

2) Process Media Temperature

Very hot media, such as steam or hot water, can elevate the gauge's internal temperature leading to failure or an unsafe condition. For high temperature application, the use of a gauge "siphon" or diaphragm seal be applied.

3) Ambient Operating Temperature and Environment
It is important to know the rated ambient environment for any instrument. Elevated ambient temperatures, moisture, vibration, and corrosive atmospheres can all affect accuracy, calibration, and safety. Choose the proper case and mechanism materials if oxidizing or reducing atmospheres exist, and consider the addition of ancillary devices, such as remote diaphragm seals, to relocate the gauge.

4) Possibility of Severe Pressure Fluctuations
In applications where dramatic line pulsations or strong over-pressure conditions are a possibility the use of pressure restrictors, snubbers, or liquid-filling will extend the service life of the pressure gauge.

5) Mounting

Pressure gauges are standardly available with bottom (radial) and back connections. NPT (National Pipe Thread Taper) threaded connections are generally the standard. Many other process connections are available though, such as straight threads, metric threads, and specialized fittings. Make sure you know how the gauge is being connected. When mounting, pressure gauges should be almost always be mounted upright.
