This “TEST INSTRUMENTATION” make Propeller Type Water Current Meter is used to measure Velocity of water flow directly in m/s. The spindle carrying the propeller wheel freely rotates in the pivot assembly. The magnet and reed switch assembly produces one pulse per rotation. The rotation of the W a t e r C u r r e n t M e t e r i s s e n s e d b y s e n s o r & g i v e s p u l s e d o u t p u t s i g n a l .

As per IS: 3910-1966, the Water Current Meter employs a propeller wheel assembly that is mounted upon a pivo assembly and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current propeller wheel assembly is made of plated brass. It employs four propeller blades that are hand formedfrom sheet metal and individually soldered to a brass frame. The finished unit is then plated. The Propeller Type Water Current Meter can be suspended by means of a Fish weight (sold extra) wading into a stream, or by a cable and wading rod from an overhead structure. A tailpiece assembly assures proper alignment of the meter to water flow when suspended by a cable. Velocity is determined by counting the number of revolutions of the propeller wheel over a given period of time. Revolutions can be monitored by several means.“TEST INSTRUMENTATION” make Digital Water Velocity Indicator / Logger (sold extra) by configuring the indicator with calibration equation (provided with each meter), it will result the direct current velocity of the stream in Meter per second. The meter is made from brass and stainless steel and all exposed surfaces are chromeplated for corrosion-free service. A standard rating table can be provided (chargeable extra) to convert propellerrevolutions to stream velocity in Metric units (meters per second). Standard system comes with spare parts,instrument oil, cleaning cloth, screwdriver and a rugged carrying case.

“TEST INSTRUMENTATION” make Vertical Axis-Cup Type Water Current Meter is used to measure Velocity of water flow directly in m/s. The spindle carrying the cup wheel freely rotates in the pivot assembly. The magnet and reed switch assembly produces one pulse per rotation. The rotation of the Water Current Meteris sensed by sensor & gives pulsed output signal.

As per IS: 3910-1992, the Cup type Water Current Meter employs a bucket wheel assembly that is mounted upon a shaft and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current bucket wheel assembly is made of plated brass. It employs six hollow conical cups that are handformed from sheet metal and individually soldered to a brass, star-shaped frame. The finished unit is then plated. The frame is shaped so that a strut connects the apex of each cup to the outer diameter of the following cup around the frame.

The Cup type Water Current Meter can be suspended by means of a Fish weight (sold extra) wading a stream, or by a cable and wading rod from an overhead structure. A tailpiece assembly assures proper alignment of the meter to water flow when suspended by a cable. Velocity is determined by counting the number of revolutionsof the bucket wheel over a given period of time. Revolutions can be monitored by Digital Rev / Time Counter (RTC-K13) (Sold Extra) or with the help of “Virtual” make Water Velocity Logger (DVI-K13) (Sold Extra) by configuring the logger with calibration equation A standard rating table can be provided (chargeable extra) toconvert propeller revolutions to stream velocity in Metric units (meters per second). Standard system comes withspare parts, instrument oil, cleaning cloth, screwdriver and a rugged carrying case.

Pigmy Type water current meter along with Micro-controller based Digital Counter or Water Velocity Indicator has been designed to measure the Velocity of water in a flowing stream or open Canal. It comprises a Pigmy Type Water Current Meter with wading Rod and & Digital Counter / Digital Water Velocity Indicator (As per Customer Requirement). Water Current Meter employs a bucket wheel assembly that is mounted upon a shaft and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current bucket wheel assembly is made of plated brass. It employs six hollow conical cups that are hand formed from sheet metal and individually soldered to a brass, star-shaped frame. The finished unit is then plated. The frame is shaped so that a strut connects the apex of each cup to the outer diameter of the following cup around the frame.

The pygmy Water Current Meter can be suspended by wading rod from an overhead structure. Velocity is determined by counting the number of revolutions of the bucket wheel over a given period of time. Revolutions can be monitored by several means (sold separately).

Other Details: • This Sun-Shine Recorder is manufactured as per IS:7243:1974. • This instrument is used to measure Sun shine intensity over day. Main Components are bowls which are manufactured from Gunmetal and are precisely machined and assembled. Base is made of marble. The Special Solid glass sphere bowl is made uniformed and well annealed and air bubble free glass having good surface finish. • The chart paper is inserted in the groove. The sun ray's intensity causes a dark spot (due to burning) on Chart paper for full day. According to the dark spot width, intensity of Sun is measured using supplied Sunshine Measuring Scale. • The instrument is supplied with one year recording graph.

This is a reliable instruments for measuring water level and total depth in boreholes wells, reservoir Etc .

Boreholes wells reservoir, etc. for the measurement the bob is lowered to the water level , when touching the level A sensor effects the illumination of a single lamp . an additional acoustic single will be Released by a buzzer when the probes is touching the water level there is a connection between the of the probes and the sensor body thereby a circuit of the lamp and the buzzer will be closed probe is of stainless  steel having A length of 15cms , the sensor is fitted at a distance of 6cms from tip . The sensor is fitted  inside so it my give us complete accuracy. the length of the wire will start from sensor . Response is seen on  led plus an audible tone is heard feature:

Cable length: 50, 100, 150, 200, 250, 300meter with marking on ever 1 meter.
