Thermatel® TD1/TD2 Flow/Level/Interface Switches

---

 

Thermatel Model TD1/TD2 flow/level/interface switches provide a new level of performance and reliability not found in previous switches. Continuous diagnostics with fault indication, temperature compensation, narrow hysteresis and fast response time make the TD1/TD2 the latest in thermal dispersion switch technology.

Measurement Principle:
The Thermatel sensor consists of two RTD elements. One is the reference and the second is heated to a temperature above the process temperature. The electronics detect the temperature difference between the two elements. The temperature difference is greatest in air, then decreases when cooling occurs due to a change in media. An increase in the flow rate further decreases the temperature difference.

The set point is adjusted for the switch to alarm at the desired temperature difference. Once the set point is reached, the relay will change state.


Features:

Temperature compensated to provide repeatable alarm under varying process temperatures
Continuous diagnostics detect sensor fault
Non-linear mA output signal can be used for trending, diagnostics and repeatable flow/level indication
Detects minimum flow or presence / absence of flow
Easy / fast calibration
Excellent low flow sensitivity


Applications:

Pump protection
Cooling water / Cooling air
Chemical feed pumps
Relief valve monitoring
Lubrication systems
Exhaust flow monitoring


Options:

Hot tap retractable probe
Sanitary design
NACE construction
Window to view alarm status
Integral or remote electronics
Flow body for very low flow detection

Thermatel® TA2 Mass Flow Transmitter

Thermatel® TA2
Mass Flow Transmitter

Thermatel Model TA2 Thermal Mass Flow Transmitter provides reliable mass measurement for air and gas flow applications. The powerful, yet easy to use, electronics are contained in a compact explosion proof enclosure. The TA2 is available with both insertion probes as well as flow body design for smaller pipe sizes. The TA2 offers excellent performance at an exceptional value.

The TA2 offers the user the ability to verify calibration in the field reducing the need for periodic recalibration.

Measurement Principle:
Thermatel Model TA2 mass flow transmitter measures mass flow by detecting heat dissipation from a heated surface. The sensor contains two mass balanced elements with precision matched RTDs. The reference sensor measures the process temperature (up to +400° F [+200° C]); the second RTD measures the temperature of the heated sensor. The power to the heater is varied to maintain a constant temperature difference above the reference temperature.

There is an inherent non-linear relationship between power and mass flow. The microprocessor in the TA2 compares the power against the calibration curve and converts the power requirements to the mass flow rate. Temperature is also measured to provide temperature compensation of the mass flow over the operating range of the instrument.

Features:

• Direct mass flow measurement of air and gas
• Excellent low flow sensitivity
• Process temperatures to +400° F (+200° C)
• Rotatable housing
• FM/FMc/ATEX approvals
• Resettable and non-resettable totalizers

Applications:

• Combustion air
• Compressed air/gas
• Natural gas
• Digester/Biogas
• Hydrogen lines

Options:

• Pulse and second mA output for temperature
• Plug in display with keypad
• HART/AMS/PACTware communications
• Remote electronics

Model R82 Pulse Burst Radar Transmitter

---

Model R82 Pulse Burst Radar Transmitter Radar has been part of the level measurement market for more than thirty years. The early designs used in tank gauging were heavy, expensive, power-hungry and complex. Advancements in radar circuitry have evolved the modern radar transmitter so that now it is light, inexpensive, loop-powered and easy to use. The R82 is the logical extension of that evolution. Microwave-based radar is a superior measurement technology with its ability to operate effectively in a wide range of process conditions. It has been too expensive to use as a replacement for ultrasonic transmitters in simple, daily applications....until now. The R82 radar transmitter can be considered the answer to almost every, daily level measurement application imaginable.

OFS 2000F Optical Flow Sensor

 

OSi's patented Optical Flow Sensor (OFS) makes drift-free measurements across the entire stack, duct or pipe diameter and calculates an accurate average flow reading. It is the only flow sensor that gives a true non-contacting cross-stack flow measurement of the process. The OFS uses our EPA Method 14 approved optical scintillation technology. The optical scintillation technique relies on advanced Digital Signal Processing (DSP) electronics to "see" and measure the movement of turbulence found in a gaseous flow stream to provide highly accurate, pathaveraged air velocity measurements. The accuracy of the OFS has been proven both in NIST’s wind tunnel and in numerous real-world installations.

Memeco Sales is proud to offer the Hamilton ARC System:

We currently have a demo unit in stock and can come to your office for a demonstration.

The true power of the HAMILTON ARC family
HAMILTON has delivered quality products to laboratories for more than 50 years, including products such as syringes, laboratory devices, automation platforms and sensors.

In the world of process analytics, HAMILTON is known for sensors (pH, oxygen, redox, and conductivity), and for its first-class choice of process armatures, completed with their selection of process connectors.

HAMILTON ARC revolutionizes the integration of sensors by rethinking communication between sensors, end users and process control systems. The functionality of a traditional transmitter has been replaced by a microprocessor within the sensor. ARC sensors bypass the transmitter and communicate directly to the control system. Sensors are available in all standard pH, dissolved oxygen and conductivity formats.

The bridge between process parameter and process control
Three ARC concepts meet customer requirements from established research and pilot labs to new production facilities and instal lations:

Ultrasonic Streamflow Monitoring System

In this study, we developed a system of continuous accurate monitoring of streamflow, which is composed of a pair of ultrasonic Doppler velocity sensors installed on an existing low head broadcrested agricultural small dam. In case of using this dam, errors in computing area are minimized due to stability of it, so that discharge can be accurately measured. In addition, by direct measurement of velocity over dam crest, this system can measure discharge not only for modular flow in which free fall occurs, but also for submerged flow affected by downstream as far as depth and velocity are measured. Preliminary results for 15 dam release events display that discharge obtained by this system is in quite good agreement with dam release and with H-Q relationship. Comparison of volumetric discharge is also made and relative difference with dam discharge is 2.7%.

Alsonic-DSP Ultrasonic Flowmeter

The SMC Alsonic DSP series

is a fixed-mount, transit-time ultrasonic flowmeter with clamp-on transducers for non-invasive liquid measurement. This device uses patented "fine time measurement technology", making use of ultrasonic beams that can measure at pico-seconds time intervals. This rapid array of measurements enables accurate, drift-free flow rate data in liquids that contain a second phase of entrained solids or gas bubbles. The use of DSP technology enables "Cross Correlation" of ideal signals to cancel extraneous noise signals, and create a three-dimensional cross section of the velocity distribution profile of the medium flowing through the pipe. DSP technology also enables the use of "FFT (Fast Fourier Transforms)" in order to generate the two signals at the same frequency; thereby increasing the signal-to-noise ratio for accurate, drift-free flow measurement in liquids.
