Tech Tip

Hi , 


Problem:  We're experiencing signal drift between the  4-wire field transmitter and the grounded receiver on our newly commissioned loop. What's causing this problem?


 Moore Isolator



Solution: The difference in potentials between two grounded, non-isolated devices may result in a ground loop.  Installing a SIY or SIX to break the galvanic path prevents the effects of ground loops, motor noise, and electrical interference.


This is just one of many Problem Solvers  featuerd by Moore Industries. 


Puls DIN Rail UPS Provides Backup Power
Puls UPS
Puls DIN rail mounted UPS

Puls has introduced an innovative UPS design which has greatly simplified the process of providing back up/emergency DC power to critical hardware in the field. This product enables you to keep devices up and running even when main power is lost. The Puls DC - UPS Control Unit design utilizes a single 12 Volt battery to provide 24 Volt DC power to PLCs, radio based telemetry systems and other sensitive systems where the loss of data and long restart cycles can not to tolerated.


This unique UPS system provides:


- DIN Rail Mounted package for compact installation

- Requires only one 12 Volt battery for a 24 Volt output  

   (No     need to match batteries)

- Complete battery diagnostics - including a signal when to replace the battery

- Electronic overload and short circuit protection

- 50% power reserves

- Selectable Buffer Time Limiter

- 3 year Warranty

Veris Accelabar Flowmeter

  Veris Accelabar

The Accelabar consists of a unique toroidal nozzle design and a Verabar averaging pitot. The nozzle has a patented "settling distance" that accelerates, linearizes and stabilizes the velocity profile sensed by the Verabar. The Verabar located within the nozzle accurately measures and significantly increases the differential pressure output to increase the operating range, with turndowns of up to 65:1.


The Accelabar can be used in extremely limited straight run piping configurations. The straight run is integral to the meter. No additional straight run is required. The Accelabar is ideal for the following flow applications:

Drexelbrook U-sonic Liquid Level & Open Channel Flowmeter


Drexelbrook Usonic
USonic 2-wire level transmitter

The Drexelbrook U-sonic family of ultrasonic transmitters is one of the most powerful and flexible units on the market today.  A few key questions customers typically ask us:


Do you need a separate hand held programmer to set-up the unit?  No, the U-sonic series is 100% field configurable via an integral keypad without requiring another device. However, the integral U-sonic is also HART compatible and can be set-up using a HART communicator or laptop software. 


How does the U-sonic handle obstructions in the tank? Incorporating automatic   "SMARTGain" technology the U-sonic will ignore any false signals from agitator blades or other obstructions in the vessel.  The "SMARTgain" causes the ultrasonic system to attenuate its gain (ability to hear the return echo). The amount of attenuation is based on the known distance from the sensor face to the actual level. By attenuating the gain we have the ability to keep return echoes decibel level seen at the transducer face within a constant decibel range. This means that when levels are close to the transducer, we use a maximum amount of attenuation and when the level is far from the transducer we use a minimum amount of (or no) attenuation.


For an open channel flow application, what if I have a non standard weir or flume?A 21-point strapping table is included for user-defined vessels, weirs and flumes.
