Apr 26, 2013 Designed for 1–12 in. pipe sizes, Series EFS2 is available in stainless steel, brass, and PVC with variety of custom fittings. Liquid flow through magnetic field produces voltage that is measured and translated into output signal. Capable of measuring flow from 0.28–20 ft/sec with accuracy of ±1% FS, series is suitable for any application where moving parts would by problematic, such as dirty liquids. In addition, sensor can handle applications where there are rapid changes in viscosity and flow.

Temperature Data Logger has -328 to +500°F measurement range.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Apr 22, 2013 Featuring external probe, submersible and portable Model HTDL-20/30 records up to 32,700 measurements in nonvolatile, solid-state relay memory that retains data even if battery becomes discharged. Logger can be started and stopped from PC or delayed to start up to 18 months after initialization, and sampling rate is selectable from 1 sec to 24 hr. Accuracy is 0.18°F from 68 to 284°F and 0.54°F from -4 to 67.98°F, and resolution is 0.02°F.

Non-Indicating 4-20 mA Transmitter can be wall or meter mounted.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Apr 12, 2013 Compatible with Series EFS2, IEFS, PDWS, TBS, and FLMG, Series BAT (Blind Analog Transmitter) takes pulse frequency output from flowmeter and converts it into continuous 4–20 mA analog output signal. Frequency for flowmeter output signal can be adjusted using 4 rotary switches on back, and MCU automatically scales all other values accordingly. Also, MCU can average inputs for more stable reading outputs; rate for averaging is adjustable and ranges from 2–16 sec.

Digital Moisture Meter also measures temperature and RH.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Apr 05, 2013 In addition to determining moisture content, from 2%–70%, in wood, gypsum, bamboo, paper, and other materials, Model MST2-01 can measure ambient temperature from 14 to 122°F and relative humidity (RH) from 10%–90%. Respective accuracies for moisture, temperature, and RH are ±1%, ±2°F, and ±5% RH. While size of digital LCD facilitates reading of measurements, hold function aids in recording displayed values. Instrument includes protective cap, 2 replacement pins, and one battery.

Paddlewheel Flow Sensor offers several material options.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Apr 05, 2013 Available with brass, stainless steel, PVC, and polypropylene materials, Series PDWS is designed for ½–8 in. pipes and suits chemical proportioning applications or any application with rapidly changing fluid conductivity. Ruby jewel bearings reduce coefficient of friction and maintain accuracy. Covering 0.3–30 fps range and delivering ±1.5% FS accuracy, series features brass, 316 SS, PVC, or polypropylene sensor; PVDF rotor; nickel-bonded tungsten carbide shaft; and EPDM O-ring.

Solar Panel Kit supports remote applications.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Mar 28, 2013 With Series SPK, it is possible to use Dwyer® flowmeters in remote applications where reliable source of electricity is not available or practical. Kit is intended for use with standard 12 V, 22–33 Ah sealed lead acid battery, which is not included. Supplied with charge controller and corrosion-resistant mounting hardware, 5 W solar panel can also be used to provide up to 40-day back-up power supply for periods of darkness.

Electromagnetic Flow Sensor measures liquids down to 0.03 gpm.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Mar 22, 2013 Available in ¾ or 3/8 in. pipe, Series LOFM liquid mag meter uses conductivity of fluids to measure flow. Liquid flow through magnetic field produces voltage which is measured and translated into pulse output signal. Housed in splashproof HDPE plastic, meter comes with variety of factory-installed adapters and O-rings. With no metal parts, unit is corrosion-resistant and compatible with wide range of chemicals. Meter also has no moving parts, making it suitable for dirty water applications.

Air Quality Transmitters measure CO2, RH, and temperature.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Mar 14, 2013 Combining CO2, RH, and temperature in one device, Series CDTR minimizes number of sensors mounted on wall or in duct. Transmitters use single-beam, dual-wavelength NDIR sensor to automatically correct measurement in both occupied and unoccupied buildings against light source aging effects. Universal outputs for both carbon dioxide and relative humidity allow users to select transmitter output to be 4–20 mA, 0–5 Vdc, or 0–10 Vdc to work with virtually any building management controller.

Paddlewheel Flow Sensor works with pipe sizes from 3-40 in.

Dwyer Instruments, Inc.    Michigan City, IN 46361
Feb 20, 2013 Available in brass, PVC, or stainless steel, Series IPFS (Insertion Paddlewheel Flow Sensor) includes hot tap model with bronze or stainless steel valve assembly. Bearings are made from ruby jewel to reduce coefficient of friction and maintain accuracy. Rotation of impeller is used to measure flow, and various saddle fittings come in iron or brass. Compatible with clean liquids, series suits chemical proportioning applications or applications with rapidly changing fluid conductivity.
