Tech Quiz

Which of the following fluid properties is important in determining if a magmeter is a good choice for fluid flow measurement?  See answer below

A) Density

B) Conductivity 
C) Viscosity

D) All of the above

 

Submersible Level Sensor
  
PBLT2
PBLT2 Submersible Level Sensor

The PBLT2 Submersible Level Transmitter is manufactured for years of trouble free service even in the harshest applications.  The PBLT2 measure the height of the liquid above its position via a piezoresistive sensing element encased in a very heavy duty 316 SS housing.  This unit is designed specifically for operation in wastewater and slurry applications.  This system is suitable in sludge pits, clarifiers, alum tanks, sumps, lime slurries, oil tanks and reservoirs.  The PBLT2 includes as standard superior lightning and surge protection utilizing dual arrestor technology - eliminating both power supply surges and lightning ground strike transients.  The unit features an extra large 316 SS diaphragm to prevent clogging and is resistant to damage from floating solids and debris.

 

The unit is equipped with a 270 pound tensile strength, shielded, vented cable. Various cable lengths are available depending on your application. The transmitter is a two wire loop powered (13-30 VDC) design for simple electrical installation.  An intrinsically safe design is available for installations in Class I, Div 1, Groups A, B, C, D; Class II, Div 1, Groups E, F, G; Class III, Div 1 hazardous locations.

Wireless Mesh I/O & Gateway
   

Elpro's 915U-2 combines multi I/O and/or gateway functionality with the reliability of secure, scalable, mesh distance communications. Featuring ELPRO WIBMesh™ technology, the 915U-2 IP based addressing provides mesh/self healing of network communications, multi-hop repeating and remote over the air re-configuration and diagnostics.

What does this mean?

Basically, the wireless I/O modules data automatically finds its way to the destination module. Should one of the repeater modules in the link fail, the data will automatically search for a new path to its destination.

The model 915U-2 module works with analog signals (current and voltage), discrete

I/O, Modbus RTU and Modbus TCP.

Features:

  • 902-928 mhz FHSS License Free
  • Full 1 watt power
  • Remote over the air configuration
  • 128 bit AES encryption

This edition, we would like to introduce you to Lauren Schultz.  She is a valued member of our Inside Sales team here at Gilson and has been with us since 2006. She works as an Inside Sales Assistant with two of our engineers, Dave Snyder and Kendra Mitchell.  She graduated from Clarion University of Pennsylvania, with a BA in English, and started with Gilson Engineering shortly after graduation.

Although she has a degree in English, she has worked hard to learn the ropes of technical sales.  She enters orders and creates quotes for Dave and Kendra's accounts along with following deliveries, scheduling repair paperwork, and handling customer phone calls.  Lauren is a hard worker, who is willing to help where she can.  With each job, she feels that she is able to learn more allowing her to be more supportive to her customers in the future.

In her spare time, Lauren is very dedicated to the Multiple Sclerosis Society.  Each year, she leads a team at the Pittsburgh MS Walk and works to raise money for her cause.  This past year, her team consisted of over sixty-five members including family, friends, and co-workers who raised just under $5,500 to help find a cure.  She is thankful to all that help her with her efforts and is looking forward to next year's walk.


Tech Quiz Answer
Answer: B, Conductivity
In most magmeters, as long as the fluid conductivity is above 5 microsiemens (micromho/cm) the magmeter will work.  The magmeter measures volumetric flow.
