Liquid Level Controller
The Model 140-LLI displays the level in a tank by sensing the head pressure and converting it to the movement of a pointer on a fixed scale, continuously indicating liquid level in an atmospheric (vented) vessel.
Because of its unique design, the Model 140-LLI has a long service life with minimal maintenance requirements. The Model 140-LLI utilizes a set of precision-crafted diaphragms as the sensing element, and the superior seal design isolates mechanical working parts from process fluids and corrosive agents in the atmosphere. Span and zero adjustment nobs are on the exterior of the unit, and if maintenance is ever required on the interior of the unit, the face plate can be easily removed.

- Knobs On The Exterior
- Secondary Diaphragm
- Leak Indicator Between The Diaphragms
The Model 140-LLI displays the level in a tank by sensing the head pressure on the diaphragm and converting it to movement of a pointer on a fixed scale, continuously indicating liquid level in an atomospheric (vented) vessel.
The Indicator is designed to have a long service with minimal maintenance requirements. Precision machining and calibration provide superior performance and accuracy of measurement while utilizing a set of precision crafted diaphragms as the sensing element, and the superior seal design isolates mechanical working parts from process fluids and corrosive agents in the atmosphere.
Operation
Head pressure moves the diaphragm (attached to a shaft) resulting in a linear motion. The shaft connects to the indicator at a pivot point. At this pivot point the linear motion transfers into rotary action, which then moves the indicator to accurately show the liquid level.
Operating Temperature:
-20°F to 225°F.
Maximum Head Pressure:
90 PSI.
Range (Vessel Height):
10-36 Feet (Other Ranges Upon Request)**
Electrical Switches:
SPDT Micro Switch; 11 Amp @ 120 to 250 VAC 1/2 Amp @ 125 VDC.
Electrical Connections:
1/2” Female NPT
Indicator Accuracy:
+ / – 2% of Full Scale
CSA Certified:
Explosion Proof Class I, Division I, Group D
Options
Connector Options:
2” FNPT Standard (Stainless Steel)
2″ Grooved End (Stainless Steel)
Scale Options:
Include feet of water, gallons, barrels and cubic meters and others.
Multiple Switch Options:
Including 2 through 7 switches.
Pulsation Dampener:
The pulsation dampener minimizes pressure spikes caused by erratic flow of liquid into or out of the vessel, delivering a constant pressure on the spring for more accurate readings.
All connections are stainless steel as a standard.
Span and zero adjustment knobs are on the exterior of the unit.
A secondary diaphragm ensures that a leak in the primary diaphragm will not result in a leak to the unit interior.
A leak indicator between the primary and secondary diaphragms lets the operator know if the primary seal is compromised.

TA-1000 PLUS
Temperature Averager
Single & Double Channel | Explosion & Weather Proof Housing
The TA-1000 is a precision temperature measuring device that provides a true volume-weighted average temperature for two separate channels using a volume input signal for each channel.
The microprocessor-controlled TA-1000 automatically calibrates the temperature probe each time temperature is sampled using two internal precision references. This technique eliminates both temperature drift and the requirement for field calibration since the probe temperature is calculated using a ratio of the probe and internal references in lieu of a fixed voltage or current level. Provide temperature, input counts, and current level. Probe temperature, input counts, total temperatures, average temperature, reset totals, flow rates, and alarms are displayed for each channel.
An internal lithium battery preserves all data and alarms during battery power failure and continues normal operation when power is restored. A fail-safe alarm relay is provided to shut down external equipment in the event of power failure, alarms, probe failure, or microprocessor failure.
