Tension weigh modules in combination with tension load cells convert suspended tanks or hoppers into scales. Tension weigh modules fully support the weight of a suspended structure, and mounting hardware ensures that only vertical load is measured, providing reliable weighing results.
The mounting hardware includes a bonding strap, PTFE-lined bearings, and PTFE washers to reduce the risk of electrical damage. The bonding strap helps to protect the load cell by shunting electrical currents directly from the top clevis to the bottom clevis, instead of through the load cell.
Each weigh module is equipped with a pair of clevis and rod assemblies that are designed to measure only vertical loads and restrain the vessel from moving. The zinc-plated carbon steel hardware is strong enough to support a vessel safely.
Mettler Toledo provides components such as weigh modules, junction boxes and terminals to turn your process or storage tank into a scale. Were you ever wondering how to calibrate your tank scale and achieve precise weighing results even for high capacities? We have the answer to your question. Instead of using dead weights or filling expensive material in the tank, the downward force is applied by hydraulic equipment. With Mettler Toledo RapidCal tank scale calibration, your tanks and silos can be calibrated up to 32 ton. We will bring the calibration equipment to your location. From you, we only need the attachment points on the foundation and on the tank. The RapidCal equipment is connected to the solid anchor point on the foundation. To attach the equipment to the tank, threaded rods are connected. The rod is mounted on the tank. The hydraulic cylinder and the reference load cell complete the calibration equipment. After that, the hydraulic components, such as cylinder, hoses, manifold, and hand pump, are connected. By increasing the hydraulic pressure, force is applied, which is monitored by reference load cells. The calibration terminal values are compared to the tank scale terminal. Our experts do the calibration. and quickly and efficiently for you. The RapidCal tank scale calibration method can be used in the 1 to 32 ton capacity range. The equipment used in this method can achieve 0.1% accuracy. RapidCal costs you less than other calibration methods, such as calibration with a flow meter or with dead weights. It is up to three times faster than, for example, the flow meter calibration. RapidCal does not interfere with your tank content. The need of costly calibration materials, for example, purified water, is eliminated and the material in the tank is not jeopardized. By doing that, the created waste is reduced too. It is the most accurate calibration method in this capacity range. RapidCal is traced back to national and international weight standards. The resulting calibration certificate complies with quality system requirements. A new age has arrived in tank weighing. Join the revolution and make your tanks ready for RapidCalTM Tank Scale Calibration to achieve a new level of accuracy and reduce significantly the calibration costs. 7 rock solid reasons to choose force calibration: 1. Cost reduction. No purified material is needed for the calibration and intense cleaning of the tank is omitted, which saves material costs and reduces environmental impact. 2. Ease of process. Reduce the headaches that usually come to you when organizing traditional calibration, either preparing for a fill calibration, organizing the delivery of purified water or with test weights. 3. Faster calibration. Shorter downtime, up to 3x times faster than, e.g., a flowmeter calibration. Typical time for RapidCalTM Tank Scale Calibration is between ~2 and 4 h, meaning you can calibrate several scales in a single day. Faster calibration reduces losses due to shut down production. 4. Zero contact with tank content. RapidCalTM Tank Scale Calibration eliminates any contact with materials in the tank, so expensive content is not jeopardized. Additionally, reducing safety and environmental risks. 5. Compliance with quality systems. Tank scale recalibration in regular intervals and the issued RapidCalTM Tank Scale Calibration certificates comply with your quality system requirements. 6. Accurate tank calibration. RapidCalTM Tank Scale Calibration is an accurate, 0.1%, full range calibration method for tank scales in the 1? 32 tons range. In most cases, this accuracy is up to 3x better when compared to a flowmeter calibration. 7. Traceable calibration. The RapidCalTM Tank Scale Calibration equipment is regularly calibrated against high precision test weights, thus your tank scale calibration is traced back to international weight standards.
Traditional calibration methods are time-consuming, expensive, and typically deliver uncertain accuracy and traceability results. The innovative RapidCal™ method from METTLER TOLEDO offers economical tank scale calibration that is traceable and achieved without using test weights or purified liquids. Additionally, by eliminating costly material substitution, contamination risk is eliminated.
