What to do if HF Scientific TV Tuner readings fluctuate and are unstable?
If the readings from your HF Scientific TV Tuner fluctuate and are unstable, it could be due to incomplete mixing of coagulant with sample water, or the sensor and/or sample chamber may require cleaning. You should also check the coagulant dosing operation.
What to do if my HF Scientific MicroTSCM analyzer display is not lit?
If the analyzer display of your HF Scientific TV Tuner is not lit, ensure the unit is plugged in and turned on, and that the power source is providing the correct voltage. Also, make sure the analyzer is set for the correct voltage and check the analyzer fuse.
Why does the reading on my HF Scientific MicroTSCM not change with a change in dosing?
If the reading on your HF Scientific TV Tuner doesn’t change with a change in dosing, the sensor may require cleaning. Also, check the sample flow to the sample chamber and ensure complete coagulant mix with water.
What to do if the sensor probe is not moving on my HF Scientific MicroTSCM?
If the sensor probe is not moving on your HF Scientific TV Tuner, check the interconnect cable connection at the sensor. Also, check the wiring of the interconnect cable on the back of the analyzer and inside the sensor, and ensure the probe is not jammed.
What to do if readings are different than expected on HF Scientific MicroTSCM TV Tuner?
If the readings on your HF Scientific TV Tuner are different than expected, the sensor may require cleaning or calibration. Check the probe and cell for wear and replace parts as required.
How to improve slow display response on HF Scientific MicroTSCM?
To improve a slow display response on your HF Scientific TV Tuner, select a lower Signal Averaging period. Also, consider that the separation between dosing and sample points might be too great.
The HF scientific MicroTSCM Streaming Current Monitor is a device designed for optimizing and controlling the dosing of coagulants used in water clarification processes. It measures the electrokinetic charge of a solution, displaying the units in either Streaming Current Units (SCU) or Ion Charge Units (ICu), with 1 ICu being approximately equal to 1 SCU. The monitor helps maintain water quality by adjusting coagulant dosage based on real-time charge analysis.
The MicroTSCM operates by continuously sampling water and directing it into an annulus where a displacement piston oscillates vertically at a fixed frequency. This action causes the liquid to move between two stainless steel electrodes. Suspended particles in the water are absorbed onto the walls, and as the sample moves rapidly back and forth, mobile counter ions surrounding the colloids are sheared near the surface of the walls and moved past the electrodes. The resulting A.C. signal, or Streaming Current, is proportional to the charge density and is electronically processed and displayed. This measurement allows for the determination of the optimum coagulant dosage to achieve charge neutralization and promote flocculation, leading to the settling of suspended particles.
The device can be integrated into an existing control scheme using its 4-20 mA or serial outputs. An optional Proportional Integral (PI) control feature allows the MicroTSCM analyzer to automatically adjust coagulant dosing. When in automatic control, the instrument monitors the process value (PV) for changes in charge and adjusts the dosage to maintain a predetermined set point (SP). This closed-loop control system mimics an operator's actions, constantly monitoring and making adjustments to keep the process reading at the set point.
The MicroTSCM system consists of three main components: the Sensor, the Sample Chamber, and the Analyzer.
