Flow Measurement Device Symbols

Flow measurement device symbols are used to signify the type and direction of fluids flowing through a pipe. These illustrations are commonly referred to as Piping and Instrumentation Diagram (P&DI) symbols and may vary slightly between organizations.

Flow measurement devices (orifice plate, pitot tube, averaging pitot tubes, flume, weir, turbine, target, positive displacement, rotameter, vortex, Coriolis, ultrasonic, magnetic, wedge, v-cone, flow nozzle, venturi, and generic.)

NIVELCO EasyTREK SP-500 Series Level Transmitters

The newest generation EasyTREK SP-500 series level transmitters are based on NIVELCO’s 35 years of experience with ultrasonic level measurement. The IP68 rated units have their transducer and processing electronics incorporated in one single housing. The new EasyTREK transmitters utilize HART® 7 communication so they can be used in multidrop systems connected to MultiCONT process controller/display, or to a PC with the help of the UNICOMM HART®-USB modem or similar. The transmitters can be remotely programmed also with Handheld Field Communicator, and can be connected wirelessly to a PC with the SAT-504 Bluetooth® HART® modem.


The ultrasonic level metering technology is based on the principle of measuring the time required for the ultrasound pulses to cover the distance from the sensor to the level to be measured and back. The echoes bounced back from the surface of the medium to be measured reach the sensor surface after the time of flight of the ultrasonic impulse. The time of flight of the reflected signal is measured and processed by the electronics, and then this is converted to distance, level, volume or flow proportional data using the customizable tank dimensions or the pre-programmed flume / weir parameters.

7 Steps for Selecting the Right Industrial Gas Detection Solution

Abstracted from the Honeywell Analytics article titled "How to Select the Right Gas Detection Solution" by Don Galman


Step 1 - Know Your Site Risks

7 Steps for Selecting the Right Industrial Gas Detection SolutionBefore beginning to consider gas detection equipment, a risk assessment needs to be conducted. Any company employing staff has the obligation to conduct risk assessments to identify potential hazards and these can include potential gas, vapor or Oxygen deficiency risks. If gas hazards are identified, gas detection is applicable as a risk reduction method.

Step 2 - Know and Identify the Primary Objective

Depending on the processes being undertaken and the gases being detected, remote or off-site alarm notification plus event data logging/reporting may also be required for Health and Safety management records. Another factor impacting on the need for enhanced reporting functions might be regulatory compliance or a condition of insurance.

Step 3 - Be Thorough and Ask the Right Questions

Having identified the primary objective, the suitable equipment is selected by asking a number of key questions. These fall into three broad categories:

  • The gases to be detected and where they may come from
  • The location and environmental conditions where detection is to take place
  • The ease of use for operators and routine servicing personnel

Step 4 - Identify the Gases to be Detected and Where They May Come From

The gases to be detected should be identified by the risk assessment, however experienced gas detection equipment manufacturers and their approved distributors are often able to help in this process, based on their experience of similar applications. However, it is important to remember that it is the end-user’s responsibility to identify all potential hazards.

It is also essential to identify the potential source of a gas release as this helps determine the number and location of detectors required for a fixed gas detection system.

Step 5 - Understand the Operating Environment

The performance, accuracy and reliability of any gas detection equipment will be affected by the environmental conditions it is subjected to. Temperature, humidity and pressure levels at the location all have a direct bearing on the type of equipment that should be selected. Additional factors such as potential variations resulting from a production process itself, diurnal/nocturnal fluctuations and seasonal changes may also affect the type of device which is suitable.

Step 6 - Understand How the Product Functions

The next area of consideration relates to additional product functionality. Aspects like wiring configuration are important, especially when retro-fitting into an existing application. If the apparatus is being integrated into a separate safety system, certain communication protocols may also be required such as HART®, Lonworks or Modbus®.

Consideration will also need to be given regarding the requirement for local displays on transmitter units and local configuration of the unit and gas displays may also be a useful addition.

Step 7 - Ease of Use

Routine maintenance is another important consideration. Some gases and vapors can be detected with a number of different sensing technologies, e.g. Hydrocarbon gases with catalytic beads or Non-dispersive Infrared NDIR. Catalytic beads do not provide fail-to-safety operation and therefore can require a high frequency of routine maintenance, however NDIR based solutions tend to have a higher initial purchase price, but may require less routine maintenance. In-house resource to undertake such routine maintenance needs to be identified and in the absence of such a resource, budgeting for third party maintenance is an important factor in selecting the right equipment.

Summary

There are many gas detection products on the market that might appear to be the same, but a closer inspection of specification, functionality and features reveals major differences in what products can do and the potential value they can offer. Similarly, individual applications are also unique in their respective designs, needs and processes undertaken.

A Great Solution for the Discontinued Moore / Siemens 353 Controller

Moore / Siemens 353
The Yokogawa YS1700 is a great alternative to the
discontinued Moore / Siemens 353.

For all of you who use the Moore / Siemens 353 controller and are concerned that you'll have to turn to eBay for spare parts, don't worry - we have a great solution. The Yokogawa YS1700 is a drop-in replacement for the Siemens / Moore 353.

The YS1700’s powerful function block programming allows for custom strategies to control many demanding processes such as boilers and steam generators, PH control, dosing control, and many other demanding plant processes. It offers extreme reliability and sophisticated control and includes employs dual CPUs for maximum reliability and hard-manual control for added protection.
