The FLT (flow/level/temperature) flow switch reliably monitors the flow and temperature of liquids, gases, slurries, lubricants, and other fluids to provide wet/dry detection and pump protection from damage due to sudden, unexpected reductions in flowrates. The FLT flow switch has a dual-alarm capability. Alarm 1 provides a pre-warning signal with the detection of low-flow situations between 0.01 and 3 ft/s, allowing the control system or operator to determine whether to keep the pump running or shut it down.

A 4-page brochure provides detailed information regarding the features and benefits of the HT and HTM mixers for processes such as chemical reactions, polymerizations, gas dispersion, mining, and waste treatment. Standard and optional shaft designs, a variety of mechanical impellers, and sealing options are also highlighted.

The Vortex mixer features both touch operation and continuous operation modes. Its low-profile design and rubber feet provide excellent stability with minimum vibration and sliding. Its highly sensitive touch switch is used to initiate real-time mixing, and its control knob allows the mixing speed to be varied. The mixer has a built-in safety device for overload protection and is constructed of a chemically resistant polypropylene exterior. A wide range of accessories, including a micro plate holder and tube holders ranging in size from 10 mm to 25 mm is available.

The patented Model 2800 inline static mixer is designed for dosing applications that require the pumping of four different chemicals into a pipe simultaneously. It can be mounted directly in a piping system, and features a fixed plate with an internal design that rapidly mixes using a combination of alternate vortex shedding and intense shear-zone turbulence. Its laying length requirements are short, and it achieves a 98%-plus dispersion of the injected fluid ten diameters downstream.

The 2GF two-gas mixer generates CO2-air mixtures with adjustable CO2 concentration in the range of 0–15%. This mixer is compatible with any microscope stage incubator, and can alternatively be used as a stand-alone device. It is accurate to within ±0.1%, and is supplied with a reusable 0.2-mm-pore polytetrafluoroethylene (PTFE) membrane filtering device.

The PremierTec magnetic mixer’s patented design features a strong magnetic coupling between the impeller and the driving magnets. This causes the impeller to levitate and thus have no direct contact with the bearing surfaces. This configuration allows for continued mixing until a tank is empty. As a result, the customer saves product, time, and money due to reduced operating costs. The mixer is suitable for processes in the pharmaceutical, biotechnology, and food industries. All products have 3.1 traceability with USP Class VI-compliant mixing components.

The Liquid Flow Controller doses small volumes at (nominal) flowrates of 10–600 mL/min (0.6–36 L/h) with a 1:10 measuring span. It performs the dynamic control or metering of liquids and is suitable for a variety of industrial applications, including heat treatment, testing, surface-coating, filling, and packaging. When combined with the manufacturer’s mass flow controller, it can simultaneously meter gases and liquids in atomizing and sterilization processes.

These custom die-cut polytetrafluroethylene (PTFE) gaskets are fabricated for a precise fit and are available in sizes from 0.25 in. to 60 in. dia. by 0.003 in. to 0.250 in. thick. They are chemically inert and unaffected by most corrosive liquids, vapors, and gases. The gaskets are made from virgin or filled PTFE, paraformaldehyde (PFA), thermally fused melamine (TFM), or expanded PTFE. The properties of these materials make the gaskets suitable for applications requiring durability and slipperiness.

This chemical treatment system accurately meters caustic soda and other pH-adjusting chemicals for water and wastewater treatment applications. Since well water is typically acidic and damaging to distribution piping, the water’s pH needs to be raised.

PDCL Series positive-displacement liquid flow calibrators cover flows ranging from 0.01 gal/min (0.04 L/min) to 400 gal/min (1,514 L/min) with an uncertainty of ±0.05% and a repeatability of 0.01% of reading. These volumetric devices displace an exact known volume of fluid, which passes through the flowmeter under test while compensating for fluid viscosity and temperature. They perform NIST-traceable calibrations of common flowmeters, including turbine, differential-pressure orifice plate, rotameter, variable area, coriolis, and any other type with a visual, pulse or analog output.
