Paddle Wheel Flow Transmitter | FSE

Paddle Wheel Flow Transmitter - Overview

Paddlewheel flow transmitters use the flow of the liquid to rotate a paddlewheel (just like a riverboat) in the flow stream. As the fluid moves faster, so does the paddlewheel. Measuring the rotations of the paddlewheel then gives an accurate indication of the speed of the flow.

Paddle Wheel Flow Transmitter - Features
- IP68 enclosure, SUS, and chemical-resistant body
- Low power consumption
- Stable & high-resolution rotor

DryLoc® pH/ORP Electrodes | Signet 2774-2777

DryLoc® pH/ORP Electrodes - Overview

These high-performance sensors are ideal for a wide range of applications. The unique foul-proof DryLoc® connector with gold-plated contacts is designed specifically for use with the Signet 2751 pH/ORP Smart Sensor Electronics or the 2760 Preamplifier. These dependable and highly responsive electrodes feature a PTFE double reference junction with potassium nitrate (KNO3 ) in the front chamber which blocks various poisoning ions such as Mercury (Hg2+), Copper (CU2+) and Lead (Pb2+). It also has a large reference chamber that extends the service life. The positioning of the temperature element allows the temperature response to be quick and accurate. The electrodes are either flat or bulb-styled. The flat versions allow sediment and particles to sweep past the measurement surface, minimising risks of abrasion, breakage and coating. The bulb versions can be used for low-temperature applications or where fast response is required. Due to the specially designed chambers which keep electrolytes in place, all sensor models can be installed at any angle, even inverted. The quick temperature response is available in either a Pt 1000 or 3KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments.
